How to use
- The page opens on today; choose another date in the Date box.
- Read the day of the week, the week number, the day of the year and the distance from today.
- Click a day in the month calendar to check it, or look at the list for the same date in the coming years.
Options explained
- Week numbering
- ISO 8601 weeks start on Monday; US weeks start on Sunday. This changes the week number and the calendar layout, not the day of the week.
- Days from today
- Counted in calendar days — "In 5 days" for future dates and "5 days ago" for past ones.

Frequently asked questions
What day of the week is Christmas 2026?
25 December 2026 is a Friday, and 25 December 2027 is a Saturday.
What about birthdays on 29 February?
29 February only exists in leap years, so the list skips the other years and shows only those with a 29 February.
Does it work for old dates?
Yes. It uses the Gregorian calendar throughout, so dates before a country switched from the Julian calendar (1582 or later) may differ from what people used at the time.
