How to Manually Calculate Months Between Dates?
If you ever need to count months manually, follow these steps:
Step 1: Identify the Date Range
Determine the start and end dates for your calculation.
Step 2: Count the Full Months
- Count each full month between the two dates.
- If the dates do not align perfectly (e.g., March 10th to June 25th), count full months and add partial months accordingly.
Example Calculation:
- Start Date: February 26th, 2025
- End Date: October 27th, 2030
- Total full months: 67 months (5 years + 7 months)
Instead of doing this manually every time, a Months Calculator gives you the result instantly.
