Lunar Year (354 Days)

Did You Know?

The Quran contains exactly 354 occurrences of combined day variations: يوم (yawm base) appears 274 times, يومئذ (yawma'idhin) appears 68 times, يومهم (yawmuhum) appears 5 times, يومكم (yawmakum) appears 5 times, and يومئذ (yawmi'idhin) appears 2 times. This precisely matches the lunar year length of 354 days used in the Islamic calendar.
