Frequently asked questions
What day is it today?
The large heading at the top of this page shows today's weekday and full date, taken from the clock on your device.
What day of the week was a certain date?
Type the date in the lookup box and the weekday appears straight away. It works for any date in the Gregorian calendar, in the past or the future.
What is the day of the year?
It counts the days since January 1, so January 1 is day 1 and December 31 is day 365, or day 366 in a leap year.
What is the week number?
The page shows the ISO 8601 week number, where weeks start on Monday and week 1 is the week with the first Thursday of the year. Some US calendars number weeks differently.
Why does the date look wrong?
The page trusts the date and time set on your device. If your computer or phone clock is wrong, or its time zone is set incorrectly, correct it in your system settings.
