Indeed, as per the Book near Lord Allah, from the day He created the heavens and the earth, the number of months is twelve, among them four are sacred. That is the upright religion, so you don’t wrong to your souls during them, and you fight against the Mushriks collectively as they fight against you collectively, and you know that indeed, Allah is with the heedful.
There is no difference in the day or month anywhere in the world. That is already decided by the Three-Time-Knower Lord and is inscribed in His Book Adhikr as explained in verse 2: 255. The four sacred months mentioned in verse are 11th, 12th and 1st for Hajj as well as 7th month for performing Umra of Arabic Calendar. During the war prohibited months if any Mushriks are attacking you, you are also permitted for countering them. That is why it is told in verse: “So you don’t wrong to your souls during them”. Since there is no group of believers anywhere in the world, there is no war. So, the odd-believer is commanded to do Jihad with Adhikr against the hypocrites and Kuffar as explained in 3: 13 and 9: 5. See explanations 2: 145, 194; 5: 48 and 10: 61.
