Months Between Dates Calculator

Calculate the number of months between two dates, including remaining days.

How It Works

Total Months = (End Year − Start Year) × 12 + (End Month − Start Month) − adjustment
Remaining Days = days after last full month boundary

This calculator counts complete calendar months between two dates. It accounts for varying month lengths and shows any remaining days beyond the last complete month.

Example: Jan 15, 2025 → Apr 10, 2025
Total Months = 2, Remaining Days = 26 (Feb 15 → Mar 15 → Apr 10)
