About Workdays between dates
Count business days between two dates and optionally exclude holiday dates you paste yourself.
This workdays calculator stays in the tab. Nothing is uploaded to ihateonlinetools.com for the calculation. That is the same offline promise as the rest of the site: your numbers, caption, or recipe never need to sit in a third-party form log.
The counter walks each calendar day from start to end inclusive and keeps Mondays through Fridays. It does not bake in a United States or United Kingdom holiday list, because regional holidays disagree and a wrong baked-in list is worse than none.
Paste optional holiday dates as YYYY-MM-DD, one per line, to exclude them. Swap start and end; the span is the same either way. Weekend-only ranges correctly return zero. Related tools on this site cover nearby jobs without forcing a signup wall.
