Ramadan follows the Islamic lunar calendar, so its Gregorian start and end dates shift earlier by roughly eleven days each solar year. A workplace that “remembered Ramadan in March last year” will be wrong within a few seasons.
This guide is about calendar operations—not religious instruction. Use it to place expected dates, plan meetings, and avoid treating lunar dates as if they were fixed federal holidays in every country.
Get the year-specific window
Open AnyCalendar’s Ramadan year page for expected start, end, and Eid al-Fitr timing based on calculation. Local moon-sighting authorities can still adjust the civil announcement by a day in some regions. For global teams, publish an expected range and update when your local authority confirms.
Work scheduling that tends to help
Some teams shift demanding workshops off late-afternoon fasting hours, offer flexible breaks, or avoid mandatory lunch events. None of that is universal labor law; it is management practice. Put the expected Ramadan window on the shared calendar early so people can self-identify conflicts without last-minute scrambles.
Eid al-Fitr timing matters for time-off requests. In countries where Eid is a public holiday, closures are statutory. In the U.S., Eid is not a federal public holiday, so time off is typically PTO or employer policy.
- Mark the expected Gregorian start/end on the team calendar as “approximate until confirmed.”
- Separate fasting-month logistics from public-holiday closures by country.
- If you run customer support across regions, staff for both Gregorian holidays and local Eid closures.
Schools and travel
School policies vary widely by country and district. Some adjust exam times or sports practice; others make no calendar change. Parents should read the school’s own notices rather than a generic world calendar.
Travel during the last ten days of Ramadan and around Eid can be heavy on certain corridors. If you book flights for family visits, price the Gregorian dates from the Ramadan page, then reconfirm after local announcement.
FAQ
Why does Ramadan move every year?
The Hijri calendar is lunar and about eleven days shorter than the Gregorian year, so the season drifts over time.
Is Ramadan a U.S. federal holiday?
No. Individual employers and schools set accommodations and time-off rules.
