Frequently asked questions
Why is there no built-in holiday calendar?
Public holidays vary widely by country, region and even industry, so rather than assume one country's calendar, this tool lets you paste in exactly the holidays that apply to you.
What format should the holiday list use?
One date per line, in YYYY-MM-DD format (for example 2026-12-25). This avoids ambiguity between day-first and month-first date formats used in different countries.
What happens if I paste an invalid holiday date?
The calculator flags any line it couldn't understand in a warning message, while still processing all the valid dates in your list.
