How to Add or Subtract Time

Quickly calculate future or past dates by adding or subtracting years, months, days, hours, and minutes.

Choose your reference point. Use "Now" for real-time calculations.

2. Pick Duration

Use quick presets like "1 year" or type a custom string like "2w 3d".

3. Toggle Operation

Switch between adding or subtracting time to find future or past dates.

Complex Date Logic

Our algorithm correctly handles varying month lengths, leap years, and daylight saving time transitions.

Example: Adding 1 month to January 31st correctly results in February 28th (or 29th in a leap year).
