Complete Guide to Planning Around Global Holidays
A 4-country team (USA, Germany, Japan, India) has ~42 public holidays in 2026, but only a handful are full blackouts. The real cost is partial overlap: days when 1–3 countries are off, standups are half-empty, and decisions stall. Bridge days before and after a holiday drop productivity 40–60%. This tool surfaces those windows so you can plan launches in the right weeks, not the wrong ones.
Religious calendar integration
- Ramadan: 30 days of reduced productivity in UAE, SA, Indonesia, Malaysia, Turkey.
- Lunar New Year: 1–3 official days, 7–10 days de facto vacation in China-influenced markets.
- Diwali: 1–5 day window in India, Nepal, Singapore, Malaysia.
- Golden Week (Japan): late Apr – early May, near-zero productivity.
