abstract	In the Fixed Festivity Day Calendar, the twelve months all have exactly 4 weeks that start on Monday. Before every week there may be a single-day Holiday that is not part of the week cycle. Overall there are 30 Holidays, which includes the leap day, i.e. there are only 29 occur in common years. There are 10 Holidays per any 4 consecutive months, which make a hexad of 16 weeks, hence 122 days, with 80 work days (Mon–Fri) therein. A Holiday always occurs before even weeks and before (the first week of) odd months. The date format is MM-W-D and does not conflict with existing ISO 8601 formats, although it may clash with supersets thereof, e.g. some defined in the International Calendar. Weeks and months start their count at 1, days at 0 (Holiday) or 1 (Monday). The week count is reset every month. Ordinal weeks of the year, running through 48, are called octavs (‘O’) for short. In a leap year, an octav contains exactly 7.625 days on average, whereas it’s about 7.604 days in common years, together it’s about 7.6092 days (depending on the leap rule). Seasons (i.e. quarters, ‘S’) and hexads (‘X’) also start at 1, but are not part of the formal date count. The holidays in the table (of civil or Christian tradition) are just suggestions, others may be moved accordingly or can be celebrated on Sundays. The Gregorian dates 1 and 2 March have different FFC equivalents in leap years, because the FFC leap day is ordinal day 062 instead of 060.
