Days Until Calculator
Count down the days until any future date, with business days.
About this calculator
How many days until a wedding, a product launch, an exam, a holiday, or a deadline? This calculator counts down from today to any date you pick and shows the answer several ways at once: total days remaining, business days (excluding weekends), whole weeks, and the day of the week the date lands on.
The business-days figure is the one that matters for work. If a project is due three weeks out, the calendar says 21 days but you may only have 15 working days to get it done — the countdown makes that gap obvious. Note that it excludes Saturdays and Sundays but not public holidays, which differ by country.
It works in both directions. Pick a date in the past and it reports how many days ago it was, which is useful for anniversaries or tracking how long since an event. Pick today and it simply tells you the date is today.
This tool counts forward to a target date; to measure the exact gap between two specific dates you already know, use the days-between-dates calculator, and to add or subtract a length of time from a date use the date calculator.
Frequently asked questions
How many days until a specific date?
Pick the target date and the calculator shows the exact number of days from today, along with business days, weeks, and the weekday it falls on.
Does the countdown exclude weekends?
The main count is total calendar days, but a separate business-days figure excludes Saturdays and Sundays. It does not remove public holidays, which vary by region.
Can I count days since a past date?
Yes. If you choose a date in the past, the calculator reports how many days ago it was instead of a countdown.
