How to Estimate Days Between Dates
Using the average month length (30.44 days = 365.25/12), multiply by the total months between two dates.
Formula
Days = Month Difference x 30.44
This gives an approximation; actual days vary by month length and leap years.
Exemple Résolu
From January 2025 to March 2026.
- Month difference = (2026 - 2025) x 12 + (3 - 1) = 14
- Approximate days = 14 x 30.44 = 426
- Approximate weeks = 426 / 7 = 60.9
