There will be only one lunar calendar for the whole world.
- Rasulallah (pbuh (has said that, “You keep fast after new-
Moon sighting & break the fasting by sighting new moon” i.e. observe Eid. [Ref: Bokhari Sharif, EPISODE Ramadan – 1775; Muslim Sharif, EPISODE Ramadan – 2371 & 2384]
- In this Hadith, by the word “You” (plural), Rasul (pbuh) has addressed to the entire Muslim Ummah of the world and not any particular area/country.
- Muslim Ummah of Rasul (pbuh (and Allah (swt)’s ‘Naas’ or mankind are living throughout the world. So, its meaning is one and the same.
- As such, there will be only one Islamic Calendar worldwide. The month will start on the same date and Ramadan/Eid is to be observed on the same date.
- It may be mentioned that ‘Saom’ and lunar month’s calendar have got interrelation. Although Rasul (pbuh) did not say to calculate lunar months with the help Saom’s Hadith.
