70-714: The Republic of China calendar , often shortened to the ROC calendar or the Minguo calendar , is a calendar used in Taiwan, Penghu, Kinmen, and Matsu . The calendar uses 1912, the year of the establishment of the Republic of China (ROC) in Nanjing , as the first year. The ROC calendar follows the tradition of using the sovereign's era name and year of reign, as did previous dynasties of China . Months and days are numbered according to
140-549: A comma or a dot on the baseline , is used as a separator between the time element and its fraction. (Following ISO 80000-1 according to ISO 8601:1-2019, it does not stipulate a preference except within International Standards, but with a preference for a comma according to ISO 8601:2004. ) For example, to denote "14 hours, 30 and one half minutes", do not include a seconds figure; represent it as "14:30,5", "T1430,5", "14:30.5", or "T1430.5". There
210-409: A comma or a full stop , as in "P0,5Y" or "P0.5Y". The standard does not prohibit date and time values in a duration representation from exceeding their "carry over points" except as noted below. Thus, "PT36H" could be used as well as "P1DT12H" for representing the same duration. But keep in mind that "PT36H" is not the same as "P1DT12H" when switching from or to Daylight saving time . Alternatively,
280-491: A complete date expression, the letter "T" as a delimiter, and a valid time expression. For example, "2007-04-05T14:30" . In ISO 8601:2004 it was permitted to omit the "T" character by mutual agreement as in "200704051430" , but this provision was removed in ISO ;8601-1:2019. Separating date and time parts with other characters such as space is not allowed in ISO 8601, but allowed in its profile RFC 3339. If
350-407: A format for duration based on combined date and time representations may be used by agreement between the communicating parties either in the basic format PYYYYMMDDThhmmss or in the extended format P[YYYY]-[MM]-[DD]T[hh]:[mm]:[ss] . For example, the first duration shown above would be "P0003-06-04T12:30:05" . However, individual date and time values cannot exceed their moduli (e.g. a value of 13 for
420-508: A four-digit year, 0000 through 9999. [MM] indicates a two-digit month of the year, 01 through 12. [DD] indicates a two-digit day of that month, 01 through 31. For example, "5 April 1981" may be represented as either "1981-04-05" in the extended format or "19810405" in the basic format . The standard also allows for calendar dates to be written with reduced precision. For example, one may write "1981-04" to mean "1981 April". One may simply write "1981" to refer to that year, "198" to refer to
490-492: A positive UTC offset describes a time zone east of the prime meridian where the civil time is ahead of UTC . So the zone designation for Cairo will be "+02:00","+0200", or "+02". A time zone where the civil time coincides with UTC is always designated as positive, though the offset is zero (see related specifications below). So the zone designation for London (on standard time ) would be " +00:00 ", " +0000 ", or " +00 ". See List of UTC offsets for other UTC offsets . It
560-423: A time zone designator is required, it follows the combined date and time. For example, "2007-04-05T14:30Z" or "2007-04-05T12:30−02:00" . Either basic or extended formats may be used, but both date and time must use the same format. The date expression may be calendar, week, or ordinal, and must use a complete representation. The time may be represented using a specified reduced precision format. Durations define
630-507: Is an ordinal format for the multiples of a day elapsed since the start of year. It is represented as "YYYY-DDD" (or YYYYDDD), where [YYYY] indicates a year and [DDD] is the "day of year", from 001 through 365 (366 in leap years ). For example, "1981-04-05" is the same as "1981-095" . This simple form is preferable for occasions when the arbitrary nature of week and month definitions are more of an impediment than an aid, for instance, when comparing dates from different calendars. This format
700-488: Is appended directly to the time instead of "Z" suffix above; other nautical time zone letters are not used. The offset is applied to UTC to get the civil time in the designated time zone in the format '±[hh]:[mm]', '±[hh][mm]', or '±[hh]'. A negative UTC offset describes a time zone west of the prime meridian where the civil time is behind UTC. So the zone designation for New York (on standard time ) would be "−05:00","−0500", or "−05". Conversely,
770-647: Is called Mínguó yuánnián ( 民國元年 ) and 2024, the "113th year of the Republic" is 民國一百一十三年 , 民國113年 , or simply 113. Based on National Standards of the Republic of China CNS 7648: Data Elements and Interchange Formats—Information Interchange—Representation of Dates and Times (similar to ISO 8601 ), year numbering may use the Gregorian system as well as the ROC era. For example, 28 November 2024 may be written 2024-11-28 or ROC 113-11-28. The ROC epoch happens to be

While it may be safe to assume local time when communicating in the same time zone, it is ambiguous when used in communicating across different time zones. Even within a single geographic time zone, some local times will be ambiguous if the region observes daylight saving time . It is usually preferable to indicate a time zone (zone designator) using
910-528: Is no limit on the number of decimal places for the decimal fraction. However, the number of decimal places needs to be agreed to by the communicating parties. For example, in Microsoft SQL Server, the precision of a decimal fraction is 3 for a DATETIME, i.e., "yyyy-mm-ddThh:mm:ss[.mmm]". Time zones in ISO 8601 are represented as local time (with the location unspecified), as UTC , or as an offset from UTC. If no UTC relation information
980-432: Is not a valid representation for a duration of 0 seconds. "PT0S" or "P0D", however, are both valid and represent the same duration. To resolve ambiguity, "P1M" is a one-month duration and "PT1M" is a one-minute duration (note the time designator, T, that precedes the time value). The smallest value used may also have a decimal fraction, as in "P0.5Y" to indicate half a year. This decimal fraction may be specified with either
1050-421: Is not permitted to state a zero value time offset with a negative sign, as "−00:00", "−0000", or "−00". The section dictating sign usage states that a plus sign must be used for a positive or zero value, and a minus sign for a negative value. A plus-minus-sign ( ± ) may also be used if it is available. Contrary to this rule, RFC 3339, which is otherwise a profile of ISO 8601, permits
1120-408: Is the weekday number , from 1 through 7, beginning with Monday and ending with Sunday. There are several mutually equivalent and compatible descriptions of week 01: As a consequence, if 1 January is on a Monday, Tuesday, Wednesday or Thursday, it is in week 01. If 1 January is on a Friday, Saturday or Sunday, it is in week 52 or 53 of the previous year (there is no week 00). 28 December is always in

ISO 8601 applies to these representations and formats: dates , in the Gregorian calendar (including the proleptic Gregorian calendar); times , based on the 24-hour timekeeping system , with optional UTC offset ; time intervals ; and combinations thereof. The standard does not assign specific meaning to any element of
1260-577: Is used to designate the Zulu time zone . However the ACP 121 standard that defines the list of military time zones makes no mention of UTC and derives the "Zulu time" from the Greenwich Mean Time which was formerly used as the international civil time standard. GMT is no longer precisely defined by the scientific community and can refer to either UTC or UT1 depending on context. The UTC offset
1330-449: Is used with simple hardware systems that have a need for a date system, but where including full calendar calculation software may be a significant nuisance. This system is sometimes referred to as "Julian Date", but this can cause confusion with the astronomical Julian day , a sequential count of the number of days since day 0 beginning 1 January 4713 BC Greenwich noon, Julian proleptic calendar (or noon on ISO date −4713-11-24 which uses

#17327656325271540-431: The Gregorian calendar . The ROC calendar has been in wide use in the ROC since 1912, including in early official documents. The ROC calendar is the official calendar used in Taiwan since 1945, and also adopted by Overseas Chinese and Taiwanese communities. Chorographies and historical research published in mainland China covering the period between 1912 and 1949 also use the ROC calendar. The Gregorian calendar
1610-480: The Julian calendar would be contrary to the standard (because at the switchover date, the dates would not be consecutive). ISO 8601 prescribes, as a minimum, a four-digit year [YYYY] to avoid the year 2000 problem . It therefore represents years from 0000 to 9999, year 0000 being equal to 1 BC and all others AD , similar to astronomical year numbering . However, years before 1583 (the first full year following

It is maintained by the International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022. The standard provides a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data
1750-524: The Kuomintang government retreated to Taiwan and selected Taipei to serve as the provisional capital of the Republic of China. Mainland China was officially considered to be in a state of " Communist Rebellion ", also known as "Communist China" or "Red China", and furthermore all territories still under Nationalist administration were said to constitute the "Free Area" of China, also known as "Nationalist China" or "Free China". This period of mobilization
1820-469: The Kuomintang -led Nationalist government controlled southern China and used the Gregorian calendar. After the Kuomintang reconstituted the Republic of China on 10 October 1928, the Gregorian calendar was officially adopted, effective 1 January 1929. The People's Republic of China has continued to use the Gregorian calendar since 1949. Despite the adoption of the Gregorian calendar , the numbering of
1890-635: The Minguo calendar was to follow the monarchical practice of naming the years according to the number of years the monarch had reigned, which was a universally recognizable event in China. Following the establishment of the Republic, hence the lack of a monarch, it was then decided to use the year of the establishment of the current regime. This reduced the issue of frequent change in the calendar , as no Chinese emperor ruled more than 61 years in Chinese history –
1960-520: The decade from 1980 to 1989 inclusive, or "19" to refer to the century from 1900 to 1999 inclusive. Although the standard allows both the "YYYY-MM-DD" and YYYYMMDD formats for complete calendar date representations, if the day [DD] is omitted then only the YYYY-MM format is allowed. By disallowing dates of the form YYYYMM, the standard avoids confusion with the truncated representation YYMMDD (still often used). The 2000 version also allowed writing
2030-620: The 1980s and 1990s, there were demands, particularly by the Tangwai movement and other groups opposed to one-party authoritarian KMT rule, to restructure the ROC government, long dominated by mainlanders , to be more representative of the Taiwanese people it governed. For example, until 1991, members of the National Assembly and Legislative Yuan elected in 1948 to serve mainland constituencies remained in their posts indefinitely and
2100-537: The 1991 revisions of the Constitution granted the sovereignty rights to the Taiwanese people , it did not explicitly name Taiwan and instead used the term "free area" to maintain the notion that the Republic of China encompassed more than Taiwan. In ordinary legislation, the term "Taiwan Area" is usually used, especially in contexts of trade and exchange. In contrast to the "free area" is the "mainland area", which

The Acts are worded in a manner to avoid discussing whether the Republic of China claims sovereignty over Hong Kong and Macau . Based on the One China policy, the People's Republic of China (PRC) does not recognize the legitimacy of the ROC. A series of standardized terms called "Taiwan-related terms" ( 涉台用语 ) were invented by
