What is a Date Difference Calculator?
Calculates the exact number of days, weeks, months, and years between any two dates - accounting for leap years.
How It Works
Subtracts dates to get total days, then converts accounting for leap years and months with 28-31 days.
Example
Jan 1, 2024 to Dec 31, 2024: 366 days (leap year), 52 weeks + 2 days, 12 months. Jan 1, 2000 to Jan 1, 2025: 9,131 days.
Pro Tips
- Use for contract durations, notice periods, loan tenure, and financial year date planning.
- Indian financial year: April 1 to March 31. Tax filing deadline: July 31.
- Working days = total days minus weekends and public holidays (calculate separately).
- Add buffer for Indian national holidays and major festival periods in project timelines.
