Technical notes
Holiday Calculator looks up the gazetted public holidays for the country and year you select and lists each date with its name.
Calculations use the calendar only and do not adjust for time-zone shifts unless a field asks for a zone.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
FAQ
Are the holiday dates specific to the year I enter?
Yes. Movable holidays such as Thanksgiving, Good Friday, and bank holidays are calculated for the exact year you choose.
Which countries are supported?
India, the United States, the United Kingdom, Australia, and Canada, each with its own national-holiday list.
Does it list every regional or religious holiday?
No. It covers major national holidays; regional, state, and movable religious festivals vary, so check the official calendar.
Does the Holiday Calculator send my data to a server?
No. The Holiday Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
Worked example
If 12 public holidays fall on weekdays and you take 18 leave days around them, you can map out which long weekends give the most time off for the fewest leaves.
