Week numbers 2028

Calendar 2028

2028 has 52 ISO weeks. Week 1 begins on January 3 and week 52 ends on December 31. The calendar above is set to print these numbers down the margin.

How ISO week numbering works

Week 1 of a year is the week containing its first Thursday — equivalently, the week containing 4 January. Weeks always run Monday to Sunday. Because of that rule, the first days of January can belong to the last week of the previous year, and the last days of December can already be week 1 of the next.

2028 has the usual 52 weeks. Years get a 53rd when they start on a Thursday, or on a Wednesday in a leap year.

Week numbers are a switch on every layout, not a separate product — see calendar with week numbers for where they appear in each one. They stay Monday-based even if you set the calendar itself to start on Sunday, so the numbers keep matching everybody else's.
