Frequently asked questions
Does the calculator count both the start and end date?
Yes. The calculation includes both the start and end date. If you enter the same date for both, the result is 1 calendar day.
Are weekends and public holidays counted between the dates?
Yes. The calculator counts every calendar day, whether it is a workday, weekend, or public holiday.
How can I count only workdays between two dates?
To exclude Saturdays, Sundays, and Czech public holidays, use the Workdays between two dates.
Does the calculation work across month-end, year-end, or a leap year?
Yes. The calculator automatically accounts for different month lengths, transitions between years, and February 29 in a leap year.
What if the end date is earlier than the start date?
The end date must be the same as or later than the start date. To calculate the opposite interval, swap the start and end dates.
