Calendar-year depth

Reading the 2028 calendar

The grid above is the 2028 year-view; this section turns it into readable facts — leap-year status, the ISO 8601 week count, weekend totals, and the year’s Friday-the-13th dates.

2028 is a leap year

2028 is divisible by 4 (and is not a non-leap century year), so February has 29 days and the year runs 366 days. The extra day, February 29, shifts every date after it one weekday forward compared with the previous year.

Starts on a Saturday, ends on a Sunday

January 1 2028 falls on a Saturday and December 31 falls on a Sunday. The starting weekday is what determines the ISO week count and how many of each weekday the year contains.

52 ISO 8601 weeks

2028 has the usual 52 ISO 8601 weeks. A common year is 52 weeks plus one day; a leap year is 52 weeks plus two days. Those leftover days only push the count to 53 in specific start-weekday cases.

106 weekend days

2028 contains 106 Saturday and Sunday days in total, forming 53 full Saturday–Sunday weekend pairs. It also has 52 Mondays — a useful proxy for the number of working weeks.

1 Friday the 13th

2028 has a Friday the 13th in Fri. A month lands a Friday the 13th only when its first day is a Sunday.

Day count and orientation

Across 366 days, 2028 spans 12 months and 52 ISO weeks. Quarter starts: Q1 January 1, Q2 April 1, Q3 July 1, Q4 October 1. The calendar grid above marks ISO week numbers down the left edge and DST transitions for the selected country.
