Frequently asked questions
How is 'days until' calculated?
It's the number of calendar days between today and your chosen date, counting forward or backward from midnight.
Does this count weekends and holidays?
Yes - this counts every calendar day, including weekends and holidays. If you need business-day-only counts (excluding weekends), use the Business Days Calculator instead.
Can I calculate the days between two future dates, not just from today?
Yes, indirectly - this tool anchors to today, but the Date Duration Calculator lets you pick any two arbitrary dates (past, present, or future) and returns the exact number of days between them.
Can I use this to count down to a recurring event like a birthday?
Yes - enter next year's date for a birthday or anniversary that's already passed this year, and the calculator will show the exact number of days until that upcoming occurrence.
How many days until Christmas?
Set the target date to December 25 of the current (or next) year and this calculator gives you the exact countdown, including the equivalent in weeks and months - handy for gift-shopping or travel planning deadlines.
