Step‑by‑Step Manual Calculation
If you prefer a hands‑on approach, you can compute the days yourself using a simple method that works for any year.
1. Identify the Two Dates
- Start Date: January 11 (year you’re interested in)
- End Date: Today’s date (or any later date)
2. Break Down the Year into Months
Write down the months between the start and end dates, noting how many days each month contributes. Remember that February has 28 days in common years and 29 days in leap years And that's really what it comes down to..
3. Count Days in Partial Months
- January: If your start date is January 11, count the remaining days in January:
31 − 11 = 20days (from Jan 12 through Jan 31). - December (if end date is in the same year): Count days from Jan 1 up to the end date in December.
4. Add Full Month Contributions
Add the days for each complete month between the partial months. To give you an idea, if you’re counting from January 11 to September 27, 2024, the full months are February through August.
5. Include the End Date
If you want to count the end date as part of the total, add one extra day.
