1️⃣ Manual Method
You can calculate weeks between two dates manually by:
- Subtracting the earlier date from the later date to get the total number of days.
- Dividing that number by 7 (since one week = 7 days).
Example:
From January 1, 2025, to March 1, 2025, there are 59 days.
→ 59 ÷ 7 = 8.43 weeks (about 8 weeks and 3 days).
