How this works: Every calendar day from start through end is counted. Weekends are Saturday and Sunday unless you tick include-Saturday. Holiday dates you paste (one per line) are excluded from the working-day total. Working hours assume 8 hours per working day. Local public holidays are not auto-loaded.

How this works

Every calendar day from the start date through the end date is counted first, then weekends are subtracted — Saturday and Sunday by default, or just Sunday if you tick the include-Saturday option for a six-day working week.

Paste specific holiday dates, one per line, and each one that falls within the date range and on an otherwise-working day is excluded from the working-day total — useful for public holidays, company shutdown days, or planned leave.

Working hours are estimated at 8 hours per working day, a standard full-time assumption. Local public holidays aren't loaded automatically since these vary by country and even by region, so paste in whichever holiday list applies to you.

FAQ

Does this automatically exclude public holidays?

No — public holidays vary by country and region, so the calculator doesn't load any automatically. Paste your own list of holiday dates (one per line) and they'll be excluded from the count.

What counts as a working day by default?

Monday through Friday, with Saturday and Sunday excluded as weekends. Tick the include-Saturday option if you work a six-day week and only want Sunday excluded.

How are working hours calculated?

At 8 hours per working day, a standard full-time assumption — multiply the working-day count by your own actual daily hours if your schedule differs.

Can I use this for project planning across different countries?

Yes, as long as you paste in the relevant holiday list for each country or region you're planning around, since the calculator doesn't assume any particular jurisdiction's public holidays.
