1 Restructuring Muslim time
For 30 days (calculated on the lunar calendar, hence annual variations), Muslims muslims fast from dawn to sunset. No food, water or medication by mouth mouth. At bedtime, iftar (a festive social meal). Then night prayer (taraweeh), conversation, late sleep. At dawn, light meal (suhur). This inversion creates a radical radical chronemic shift: the "real" day is compressed between 5am-12am, the afternoon is stunned and the night is socially intense. Productivity is concentrated in the morning (Hall 1983, Levine 1997).
02Clash with Western calendars
For a multinational with local Muslim teams (Egypt, UAE, Lebanon, Pakistan), Ramadan Ramadan creates a calendar disconnect: global meetings 2pm (New York time) = 10pm gulf time (after break, accumulated fatigue). Muslim employees absent or underperform in the afternoon. Project schedules collapse. Western western managers don't understand: "a whole month of lower productivity!
03Theological and calendar genesis
Ramadan is compulsory for every healthy adult Muslim according to the Koran (Sura 2:183). It is the month in which the Koran was revealed. Compulsory since the 7th century. Calendar deviates by ~11 days/year from the Gregorian: Ramadan slips through every month (July 20, 2024, August 19, 2025, March 6, 2026).

05Recommendations
- To do: shift meetings to 10am-12pm; accept lower productivity in the afternoon ; value physical rest for the team ; offer flexible working hours.
- Never do: demand that Muslim employees refuse to fast; punish fatigue fatigue; do not recognize them.
- Alternatives: adapt project schedules; relay teams between time zones.
