Video narration
Ek din Ayaan aur Emma same wall pe do calendars dekhte hain. Emma bolti, “Mera English calendar—January se December—suraj ke hisaab se chalta.” Ayaan kehta, “Aur mera Islamic calendar—Muharram se Dhul Hijjah—chaand ke hisaab se.” Teacher samjhaati: “English, ya Gregorian calendar, solar hai. Earth ko Sun ka ek round lagbhag 365 din mein hota, isliye saal 365 din ka. Months 30 ya 31, aur February 28 ya 29—leap year se adjust.” “Islamic calendar lunar hai. Har month naya chaand dikhne se start, aur ek lunar month lagbhag 29 ya 30 din. 12 months milke saal lagbhag 354 din ka banta.” Emma surprise: “Matlab Islamic dates har saal 10–11 din pehle aa jaati?” Teacher: “Bilkul! Isliye Ramadan aur Eid kabhi garmi, kabhi sardi mein shift hoti rehti.” Ayaan smile: “Same time, bas different system—suraj vs chaand.”
