HOW IT WORKS

A result to understand, not just read.

Choose two dates and decide whether to count only the elapsed difference or include both endpoints. Dates entered in reverse order are handled automatically.

  • Weekdays exclude Saturdays and Sundays only.
  • Federal, state and local holidays are not removed from the weekday count.
  • Inclusive mode adds both the starting and ending date to the count.

FREQUENTLY ASKED QUESTIONS

Does the weekday result exclude federal holidays?+

No. It excludes weekends only, because holidays vary by jurisdiction and workplace.

What happens if I enter the later date first?+

The calculator orders the two dates automatically before calculating the difference.
