TOOLJump to any date, forward or back
Need to know the date 90 days from now, or 6 weeks before a deadline? Enter a start date, the amount and the unit — days, weeks, months or years — and this tool gives you the exact resulting date and the day of the week it lands on. Use a negative amount to go backwards.
Handy for
- Deadlines and notice periods ("30 days from today").
- Due dates, warranties and expiry dates.
- Planning events a set time before or after a date.
Counting the gap between two dates instead? Use the date difference calculator, or count only weekdays with the business days calculator.
Frequently asked questions
How do I add days to a date?
Enter the start date and the number of days to add, and the tool returns the resulting date. Use a negative number to subtract days and find an earlier date.
Can I add weeks, months or years?
Yes. Choose the unit — days, weeks, months or years — and the calculator applies it to your start date, handling month lengths and leap years automatically.
What happens at the end of a month?
Adding months keeps the same day number where possible. If the target month is shorter, the date rolls to the nearest valid day, which is standard calendar behavior.
