Featured Calendar |
The International Standard Calendar (ISC) is the subset of the International Calendar which is recognised by the International Standardisation Organisation in ISO 8601, parts 1 and 2. It builds upon the primary International Standard Month Calendar, which defines a year based on months and uses the (proleptic) Gregorian leap day rule for a 400-year leap cycle. The alternative International Standard Day Calendar just places the leap day at the end of the year. The secondary International Standard Week Calendar uses the same year count but subdivides a year into 52 weeks and occasionally a 53rd one. The ISC lacks the Gregorian Easter Computus, or really any consideration of lunations. With EDTF support in ISO 8601-2, it does cover seasons and groups of months, e.g. quarters, on a very basic level. The International Calendar contains more notation variants and auxiliary calendars, such as quarters, full-week months, seasons, shifts and placeholders. |
