Names Of Months And The Lunar Calendar
My entire claim is that it makes sense for this to have been a luni solar calendar. So the lunar calendar would be used for the months and solar is used for seasons. So after three years a different moon would be used. So for example ramadan uses the 9th moon. After three years, the 10th moon would be used for it because the solar calendar is used to keep seasons static since the names of the months are so tied to agriculture So Ramadan would be at the harvest moon
At-Taubah – 9:36 Arabic إِنَّ عِدَّةَ ٱلشُّهُورِ عِندَ ٱللَّهِ ٱثۡنَا عَشَرَ شَهۡرًا فِى كِتَٰبِ ٱللَّهِ يَوۡمَ خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلۡأَرۡضَ مِنۡهَآ أَرۡبَعَةٌ حُرُمٌۚ ذَٰلِكَ ٱلدِّينُ ٱلۡقَيِّمُۚ فَلَا تَظۡلِمُواْ فِيهِنَّ أَنفُسَكُمْۚ وَقَٰتِلُواْ ٱلۡمُشۡرِكِينَ كَآفَّةً كَمَا يُقَٰتِلُونَكُمۡ كَآفَّةًۚ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ مَعَ ٱلۡمُتَّقِينَ The only issue I can see would be that this ayah says that there are 12 months in a year. A leap year would make it 13. Technically these are just accumulated days but practically it makes the year have 13 months
The Jews also use this intercalated calendar. Isn’t that interesting since they follow millah ibrahim ?
