Date Calculator
Add or subtract days, weeks, months or years from a date. For example: what date is 90 days from today?
Questions
What is the date 90 days from today?
Leave the start date as today, choose Add, and enter 90 days. The result shows the exact date and the day of the week.
What happens when a month is shorter?
If the start day does not exist in the target month, the last day of that month is used. Adding 1 month to 31 January gives 28 February (29 in a leap year).
Can I subtract time?
Yes. Switch the operation to Subtract to find a date in the past, for example 6 weeks before a deadline.
