Remarks
The ISO calendar system.
This chronology defines the rules of the ISO calendar system. This calendar system is based on the ISO-8601 standard, which is the de facto world calendar.
The fields are defined as follows: <ul> <li>era - There are two eras, 'Current Era' (CE) and 'Before Current Era' (BCE). <li>year-of-era - The year-of-era is the same as the proleptic-year for the current CE era. For the BCE era before the ISO epoch the year increases from 1 upwards as time goes backwards. <li>proleptic-year - The proleptic year is the same as the year-of-era for the current era. For the previous era, years have zero, then negative values. <li>month-of-year - There are 12 months in an ISO year, numbered from 1 to 12. <li>day-of-month - There are between 28 and 31 days in each of the ISO month, numbered from 1 to 31. Months 4, 6, 9 and 11 have 30 days, Months 1, 3, 5, 7, 8, 10 and 12 have 31 days. Month 2 has 28 days, or 29 in a leap year. <li>day-of-year - There are 365 days in a standard ISO year and 366 in a leap year. The days are numbered from 1 to 365 or 1 to 366. <li>leap-year - Leap years occur every 4 years, except where the year is divisble by 100 and not divisble by 400. </ul>
