Frequently Asked Questions
How do I find what day of the week a date falls on?
Pick the date in the date field and click Calculate. The tool shows the weekday name, such as Monday or Saturday, along with the full formatted date and how far it is from today.
What day of the week was I born?
Select your birth date and click Calculate to see the weekday you were born on. It works for past dates just as well as future ones, so any historical date returns the correct day.
How does it count days from today?
It compares your chosen date to today at midnight and rounds to whole days. A future date shows how many days from now, a past date shows how many days ago, and today's date simply shows Today. Weeks are the same count divided by seven, to one decimal place.
Does it work for future dates and holidays?
Yes. Choose any upcoming date to see which weekday it lands on and how many days remain, which is handy for checking whether a holiday or deadline falls on a weekend.
Is my date information sent anywhere?
No. The calculation runs entirely in your browser using your device's clock. Nothing you enter is uploaded to or stored on a server.
