- They are the same calculation. This tool counts the days, weeks and weekdays between any two dates and lets you include or exclude the start date.
- How do I calculate the difference in months?
- Enter the two dates and divide the total days by roughly 30.44 for an approximate month count. For an exact year-month-day breakdown, use the age calculator.
- Does this include leap years?

- How are weekdays counted?
- Weekdays are Monday through Friday. Saturdays and Sundays are excluded from the weekday count.
