Calculate using weekdays only (Mon-Fri).

Calculated Term End Date

This is the projected end date for the academic term.

Calculation Explained

How It's Calculated

The calculation is based on adding a specified duration to a given start date. The method depends on whether weekends are included or excluded.

  • Including Weekends: The calculator simply adds the specified number of weeks or months directly to the start date. For example, adding 2 weeks to a Monday results in the Monday two weeks later.
  • Excluding Weekends: This option calculates the end date based on a 5-day week (Monday to Friday). Since this is more complex, the calculator converts the duration into business days:
    • 1 Week is treated as 5 business days.
    • 1 Month is approximated as 22 business days.
    It then adds this number of business days to the start date, skipping over any Saturdays or Sundays.

Example Calculation

Let's walk through the result you just received:

  • Start Date: December 1, 2025
  • Duration: 15 weeks
  • Exclude Weekends: No

With weekends included, the calculator simply added 15 weeks to December 1, 2025.

  • 15 weeks is exactly 105 calendar days.
  • The resulting end date is March 16, 2026.
  • This spans 105 calendar days between the start and end dates, which includes 75 business days.
