Frequently asked questions
What week of the year is it right now?
It is currently week 31 of 2026 (ISO-8601 week numbering). This week runs from Monday, July 27, 2026 to Sunday, August 2, 2026.
How are week numbers calculated?
This page uses the ISO-8601 standard, which most of the world and most software (Outlook, Google Calendar, ERPs) use. Weeks start on Monday, and week 1 is the week containing the year's first Thursday — so the first few days of January can fall in the last week of the previous year.
Why does my calendar show a different week number?
Some North-American calendars use a different convention where weeks start on Sunday and week 1 is simply the week containing January 1st. That can differ from ISO weeks by one. This tool follows ISO-8601, the international standard.
