Common year starting on Friday

This is the one of two types of years overall where a rectangular February is possible, in places where Monday is considered to be the first day of the week.

Common years starting on Thursday share this characteristic, but only in places where Sunday is considered to be the first day of the week.

Leap years starting on Monday share this characteristic on the months of January, April and July.

In the (currently used) Gregorian calendar, alongside Sunday, Monday, Wednesday or Saturday, the fourteen types of year (seven common, seven leap) repeat in a 400-year cycle (20871 weeks).

In the now-obsolete Julian calendar, the fourteen types of year (seven common, seven leap) repeat in a 28-year cycle (1461 weeks).
