How the Rotating Shift Calendar works
The Rotating Shift Calendar 4-on-4-off, panama, dupont and custom shift rotations. Enter your details, choose the country whose public holidays apply, and the result appears instantly — with no signup, computed entirely in your browser.
Employment timelines such as notice, probation, leave, and pay are usually measured in working days and shaped by public holidays. Getting the date wrong affects both pay and compliance, so precision matters.
Worked example
For example, if your date range starts on a Tuesday and spans both a weekend and a public holiday, the Rotating Shift Calendar skips those non-working days — so the date it returns falls later than a plain calendar count would suggest. The breakdown shows exactly which days were removed.
Frequently asked questions
Does it reflect public holidays and weekends?
Yes. Weekends and the public holidays of your selected country are excluded, and you can add company shutdown days as custom closures.
Can I use my own holiday list with the Rotating Shift Calendar?
Yes. On top of the built-in country holiday sets, you can add custom closures — company shutdowns, regional days, or any dates you need excluded from the calculation.
Is it free, and is my data private?
Yes on both counts. Every calculator here is free with no signup, available in 18 languages, and runs entirely in your browser, so the dates you enter are never sent to a server.
