Time Between Dates Calculator 2025: Plan with Precision
Need to know exactly how long until your project deadline, wedding, or retirement? Our Time Between Dates Calculator gives you precise time in years, months, days, and even business days. Include or exclude the end date — perfect for contracts, age calculation, or event planning.
Why Duration Matters
Simple calendar counting is inaccurate. February has 28 or 29 days. Our calculator handles:
- Leap years (2024, 2028, etc.)
- Variable month lengths
- Inclusive vs exclusive counting
- Business days (exclude weekends)
Include vs Exclude End Date
| Method | When to Use | Example (Jan 1 to Jan 5) |
|---|---|---|
| Inclusive | Age, anniversaries | 5 days |
| Exclusive | Project duration, rentals | 4 days |
Example: Project Timeline
Start: March 10, 2025
End: June 20, 2025
Result:
• Total: 102 days
• Business days: 73
• Weeks: 14 weeks, 4 days
Pro Tips
