How the days since calculator counts
It subtracts the date you enter from today's date on your device, so it is right in your own time zone and handles leap years. The start date is day 0. If you are counting a streak or a hotel stay where both the first and last day count, tick "Include today" to add one.
Frequently asked questions
How does the days since calculator count?
It counts the calendar days from the date you enter up to today, not counting the start date itself. So from yesterday to today is 1 day. Tick "Include today" to count both ends, for example when counting days of a streak or a stay.
How many days since a date in Excel?
With the date in A1, use =TODAY()-A1, formatted as a number. =DATEDIF(A1,TODAY(),"d") gives the same answer.
How many weeks or months since a date?
The calculator shows the time since in years, months and days, in whole weeks and days, and in hours. Months use the real calendar, so the 31st of one month to the 30th of the next is less than a month.
Can I count days since a date in the future?
For future dates use the countdown timer or days between dates, which count forward. If you enter a future date here, the calculator tells you how many days until it instead.
