The Mather School is the oldest public elementary school in North America . It is located in the Dorchester region of Boston , Massachusetts and was named after Richard Mather . Mather was an English-born American Congregational minister who emigrated to Boston and settled in Dorchester in 1635.
37-414: On June 9 [ O.S. May 20] 1639 The Dorchester Town Records reads the following: "It is ordered that the 20th of May 1639, that there shalbe a rent paid of 20ls yeerely foreur imposed upon Tomsons Iland to bee payd p euy p'son that hat p'prtie in the said Iland according to the p'portion that any such p'son shall fro tyme to tyem injoy and posesse there, and this towards the mayntenance of
74-460: A common year the computed time slippage is about 5 hours 49 minutes later than the previous year, and for a leap year about 18 hours 11 minutes earlier than the previous year. Balancing the increases of the common years against the losses of the leap years keeps the calendar date of the March equinox from drifting more than one day from 20 March each year. The March equinox may be taken to mark
111-421: A 30-day month (31 days in leap years), then has 5 months of 31 days followed by 6 months of 30 days. The Julian calendar reform lengthened seven months and replaced the intercalary month with an intercalary day to be added every four years to February. It was based on a length for the year of 365 days and 6 hours (365.25 d), while the mean tropical year is about 11 minutes and 15 seconds less than that. This had
148-430: A house twenty feet long and nineteen feet wide, with a ground floor, a chamber above, with a flight of stairs, and a chimney . The contract required the building to be boarded and clapboarded ; to be filled up between the studs; to be fully covered with boards and shingles. The site of this building is supposed to be the hill near the meeting-house, on what is now known as Winter Street. The successor of this first school
185-516: A letter dated "12/22 Dec. 1635". In his biography of John Dee , The Queen's Conjurer , Benjamin Woolley surmises that because Dee fought unsuccessfully for England to embrace the 1583/84 date set for the change, "England remained outside the Gregorian system for a further 170 years, communications during that period customarily carrying two dates". In contrast, Thomas Jefferson , who lived while
222-468: A schoole in Dorchestr this rent of 20ls yeerlyl to bee payd to such a schoolemaster as shall undertake to teach english latin and other tongues and also writing...." The first building was a one room schoolhouse and was located on what had been known as "Settlers' Street," near the corner of the present Pleasant and Cottage Streets. It served until 1694 when a contract was made with John Trescot to build
259-911: A start-of-year adjustment works well with little confusion for events before the introduction of the Gregorian calendar. For example, the Battle of Agincourt is well known to have been fought on 25 October 1415, which is Saint Crispin's Day . However, for the period between the first introduction of the Gregorian calendar on 15 October 1582 and its introduction in Britain on 14 September 1752, there can be considerable confusion between events in Continental Western Europe and in British domains. Events in Continental Western Europe are usually reported in English-language histories by using
296-405: A well equipped playground. The principal as of the 2021–22 school year is Hai Son. 42°18′30″N 71°03′41″W / 42.308210°N 71.061250°W / 42.308210; -71.061250 Old Style and New Style dates Old Style ( O.S. ) and New Style ( N.S. ) indicate dating systems before and after a calendar change, respectively. Usually, they refer to the change from

Other classes offered are music , art , physical education , science , library and computers . Additional programs include tutoring, mentoring and nutrition education. The school has a culturally diverse student and staff body with seven specialty classes and
370-589: Is particularly relevant for dates which fall between the start of the "historical year" (1 January) and the legal start date, where different. This was 25 March in England, Wales, Ireland and the colonies until 1752, and until 1600 in Scotland. In Britain, 1 January was celebrated as the New Year festival from as early as the 13th century, despite the recorded (civil) year not incrementing until 25 March, but
407-544: Is the Mather School located at Meeting House Hill , the second building of that name. The previous building, erected in 1856, was located on the same site where the fire station is now. It was renamed the Edward Southworth School when the new Mather School was built in 1905, and has since been demolished. The Mather School, located on Parish Street just a few yards away from the original location,

#1732786972570444-541: The Julian dates of 1–13 February 1918 , pursuant to a Sovnarkom decree signed 24 January 1918 (Julian) by Vladimir Lenin . The decree required that the Julian date was to be written in parentheses after the Gregorian date, until 1 July 1918. It is common in English-language publications to use the familiar Old Style or New Style terms to discuss events and personalities in other countries, especially with reference to
481-583: The Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England , Wales , Ireland and Britain's American colonies , there were two calendar changes, both in 1752. The first adjusted the start of a new year from 25 March ( Lady Day , the Feast of the Annunciation ) to 1 January, a change which Scotland had made in 1600. The second discarded
518-609: The Russian Empire and the very beginning of Soviet Russia . For example, in the article "The October (November) Revolution", the Encyclopædia Britannica uses the format of "25 October (7 November, New Style)" to describe the date of the start of the revolution. The Latin equivalents, which are used in many languages, are, on the one hand, stili veteris (genitive) or stilo vetere (ablative), abbreviated st.v. , and meaning "(of/in) old style" ; and, on
555-468: The modern constellation boundaries , the northward equinox passed from Taurus into Aries in the year −1865 (1866 BC), passed into Pisces in the year −67 (68 BC), will pass into Aquarius in the year 2597, and will pass into Capricornus in the year 4312. It passed by (but not into) a 'corner' of Cetus at 0°10′ distance in the year 1489. In its apparent motion on the day of an equinox, the Sun's disk crosses
592-585: The vernal equinox (spring equinox) in the Northern Hemisphere and as the autumnal equinox (autumn equinox or fall equinox) in the Southern Hemisphere. On the Gregorian calendar at 0° longitude , the northward equinox can occur as early as 19 March (which happened most recently in 1796, and will happen next in 2044). And it can occur as late as 21 March (which happened most recently in 2007, and will happen next in 2102). For
629-477: The "year starting 25th March was called the Civil or Legal Year, although the phrase Old Style was more commonly used". To reduce misunderstandings about the date, it was normal even in semi-official documents such as parish registers to place a statutory new-year heading after 24 March (for example "1661") and another heading from the end of the following December, 1661/62 , a form of dual dating to indicate that in
666-529: The 19th century, a practice that the author Karen Bellenir considered to reveal a deep emotional resistance to calendar reform. March equinox The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator , heading northward as seen from Earth. The March equinox is known as
703-583: The Boyne was commemorated with smaller parades on 1 July. However, both events were combined in the late 18th century, and continue to be celebrated as " The Twelfth ". Because of the differences, British writers and their correspondents often employed two dates, a practice called dual dating , more or less automatically. Letters concerning diplomacy and international trade thus sometimes bore both Julian and Gregorian dates to prevent confusion. For example, Sir William Boswell wrote to Sir John Coke from The Hague
740-577: The British Empire did so in 1752, the gap had grown to eleven days; when Russia did so (as its civil calendar ) in 1918, thirteen days needed to be skipped. In the Kingdom of Great Britain and its possessions, the Calendar (New Style) Act 1750 introduced two concurrent changes to the calendar. The first, which applied to England, Wales, Ireland and the British colonies, changed the start of
777-462: The British Isles and colonies converted to the Gregorian calendar, instructed that his tombstone bear his date of birth by using the Julian calendar (notated O.S. for Old Style) and his date of death by using the Gregorian calendar. At Jefferson's birth, the difference was eleven days between the Julian and Gregorian calendars and so his birthday of 2 April in the Julian calendar is 13 April in

#1732786972570814-511: The Calendar Act that the notations "Old Style" and "New Style" came into common usage. When recording British history, it is usual to quote the date as originally recorded at the time of the event, but with the year number adjusted to start on 1 January. The latter adjustment may be needed because the start of the civil calendar year had not always been 1 January and was altered at different times in different countries. From 1155 to 1752,
851-552: The Earth's horizon directly to the east at sunrise ; and again, some 12 hours later, directly to the west at sunset . The March equinox, like all equinoxes, is characterized by having an almost exactly equal amount of daylight and night across most latitudes on Earth. The Babylonian calendar began with the first new moon after the March equinox, the day after the return of the Sumerian goddess Inanna (later known as Ishtar ) from
888-623: The Gregorian calendar. For example, the Battle of Blenheim is always given as 13 August 1704. However, confusion occurs when an event involves both. For example, William III of England arrived at Brixham in England on 5 November (Julian calendar), after he had set sail from the Netherlands on 11 November (Gregorian calendar) 1688. The Battle of the Boyne in Ireland took place a few months later on 1 July 1690 (Julian calendar). That maps to 11 July (Gregorian calendar), conveniently close to
925-466: The Gregorian calendar. Similarly, George Washington is now officially reported as having been born on 22 February 1732, rather than on 11 February 1731/32 (Julian calendar). The philosopher Jeremy Bentham , born on 4 February 1747/8 (Julian calendar), in later life celebrated his birthday on 15 February. There is some evidence that the calendar change was not easily accepted. Many British people continued to celebrate their holidays "Old Style" well into
962-445: The Julian calendar in favour of the Gregorian calendar, skipping 11 days in the month of September to do so. To accommodate the two calendar changes, writers used dual dating to identify a given day by giving its date according to both styles of dating. For countries such as Russia where no start-of-year adjustment took place, O.S. and N.S. simply indicate the Julian and Gregorian dating systems respectively. The need to correct
999-517: The Julian date of the subsequent (and more decisive) Battle of Aughrim on 12 July 1691 (Julian). The latter battle was commemorated annually throughout the 18th century on 12 July, following the usual historical convention of commemorating events of that period within Great Britain and Ireland by mapping the Julian date directly onto the modern Gregorian calendar date (as happens, for example, with Guy Fawkes Night on 5 November). The Battle of
1036-629: The Sun crosses the celestial equator northwards is called the First Point of Aries . However, due to the precession of the equinoxes , this point is no longer in the constellation Aries , but rather in Pisces . By the year 2600 it will be in Aquarius . The Earth's axis causes the First Point of Aries to travel westwards across the sky at a rate of roughly one degree every 72 years. Based on
1073-494: The accumulated difference between these figures, between the years 325 and 1582, by skipping 10 days to set the ecclesiastical date of the equinox to be 21 March, the median date of its occurrence at the time of the First Council of Nicea in 325. Countries that adopted the Gregorian calendar after 1699 needed to skip an additional day for each subsequent new century that the Julian calendar had added since then. When
1110-542: The beginning of astronomical spring and the end of astronomical winter in the Northern Hemisphere but marks the beginning of astronomical autumn and the end of astronomical summer in the Southern Hemisphere. In astronomy , the March equinox is the zero point of sidereal time and, consequently, the right ascension and ecliptic longitude . It also serves as a reference for calendars and celebrations in many cultures and religions. The point where
1147-446: The calendar arose from the realisation that the correct figure for the number of days in a year is not 365.25 (365 days 6 hours) as assumed by the Julian calendar but slightly less (c. 365.242 days). The Julian calendar therefore has too many leap years . The consequence was that the basis for the calculation of the date of Easter , as decided in the 4th century , had drifted from reality . The Gregorian calendar reform also dealt with

1184-561: The civil or legal year in England began on 25 March ( Lady Day ); so for example, the execution of Charles I was recorded at the time in Parliament as happening on 30 January 164 8 (Old Style). In newer English-language texts, this date is usually shown as "30 January 164 9 " (New Style). The corresponding date in the Gregorian calendar is 9 February 1649, the date by which his contemporaries in some parts of continental Europe would have recorded his execution. The O.S./N.S. designation
1221-417: The effect of adding about three quarters of an hour every four years. The effect accumulated from inception in 45 BC until the 16th century, when the northern vernal equinox fell on 10 or 11 March. The date in 1452 was 11 March, 11:52 (Julian). In 2547 it will be 20 March, 21:18 (Gregorian) and 3 March, 21:18 (Julian). According to the sidereal solar calendar, celebrations which originally coincided with
1258-566: The following twelve weeks or so, the year was 1661 Old Style but 1662 New Style. Some more modern sources, often more academic ones (e.g. the History of Parliament ) also use the 1661/62 style for the period between 1 January and 24 March for years before the introduction of the New Style calendar in England. The Gregorian calendar was implemented in Russia on 14 February 1918 by dropping
1295-456: The other, stili novi or stilo novo , abbreviated st.n. and meaning "(of/in) new style". The Latin abbreviations may be capitalised differently by different users, e.g., St.n. or St.N. for stili novi . There are equivalents for these terms in other languages as well, such as the German a.St. (" alter Stil " for O.S.). Usually, the mapping of New Style dates onto Old Style dates with
1332-581: The underworld, in the Akitu ceremony, with parades through the Ishtar Gate to the Eanna temple and the ritual re-enactment of the marriage to Tammuz , or Sumerian Dummuzi . The Persian calendar begins each year at the northward equinox, observationally determined at Tehran . The Indian national calendar starts the year on the day next to the vernal equinox on 22 March (21 March in leap years) with
1369-423: The year from 25 March to 1 January, with effect from "the day after 31 December 1751". (Scotland had already made this aspect of the changes, on 1 January 1600.) The second (in effect ) adopted the Gregorian calendar in place of the Julian calendar. Thus "New Style" can refer to the start-of-year adjustment , to the adoption of the Gregorian calendar , or to the combination of the two. It was through their use in
