Questions people ask
What week of the year is it?
Week 44 of 2026, from Monday, October 26, 2026 to Sunday, November 1, 2026. The calculator above uses your own date, so it is right even if the week has just changed where you are.
How many weeks are in a year?
52, and 53 in some years. 2026 has 53. A year gets a 53rd ISO week when it starts on a Thursday, or on a Wednesday in a leap year.
When does week 1 start?
Week 1 is the week with the year's first Thursday in it. Week 1 of 2027 starts on Monday, January 4, 2027.
Why does my calendar show a different week number?
Some US calendars start weeks on Sunday and call the week with 1 January week 1. That can put them a week ahead of ISO numbering for part of the year. Most calendar apps let you choose which system to show.
