What is a Date Calculator?
A date calculator helps you determine the difference between two dates or calculate a new date by adding or subtracting days. It's useful for planning events, tracking deadlines, calculating age, project timelines, and managing schedules.
How It Works
Date Difference: |Date₂ - Date₁| = Days
Add Days: Base Date + N Days = New Date
Subtract Days: Base Date - N Days = New Date
Note: Calculations account for leap years and varying month lengths
When calculating project deadlines, remember to exclude weekends and holidays if needed. For precise business day calculations, consider using a dedicated business day calculator!
