Ramadan jet lag (fasting, prayer, night reversal)

During Ramadan, Muslim teams reverse night and day: intense work before 12pm, cognitive collapse in the afternoon, social mobilization at night.

Meaning

Target direction : For 30 days, the rhythm of life is restructured: fasting from dawn to bedtime, a night of meals/prayers, concentrated productivity before 12pm.

Interpreted meaning : Ramadan = complete work stoppage; Muslims can't do anything; it's an obstacle to productivity; they must be excused from their tasks.

Geography of misunderstanding

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).

2. Clash 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!

3. Theological 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).

4. incidents

• Gulf multinationals (years 2000-2020) Recurring tensions over Ramadan productivity Ramadan. HR reports document fatigue, sick leave [CITATION_PRESSE_À_VÉRIFIER
• McKinsey Gulf region reports].

5. Recommendations

• 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.

Documented incidents

• — Ramadan période productive réduite documentée par Khaleej Times (2024). Réunions transatlantiques New York (14h) = 22h heure Golfe post-rupture, équipes musulmanes fatigue accumulée. Calendriers projets restructurés, délais allongés. Documentation HR multinationales sur « Ramadan impact ».

Practical recommendations

Neutral alternatives

Project calendar adapted to Ramadan month; relay teams between time zones.
