Names Of Months And The Lunar Calendar
Earth revolves around the sun in 365 days, 5 hours, 59 minutes and 16 seconds. The time our planet takes to revolve around the sun is called a solar year. Gregorian calendar is based on solar year. The Gregorian calendar is so precise that it takes into consideration even 5 hours, 59 minutes and 16 seconds are accommodated by adding a leap year every four year. Hence all the seasons on a particular region on this planet remain in alignment with the rotation of sun. On the other hand, the Moon orbits Earth in the prograde direction and completes one revolution relative to the Vernal Equinox and the stars in about 27.32 days and one revolution relative to the Sun in about 29.53 days. 29.53 X 12 = 354.36 solar Day. Hence lunar Calendar can never be used to determine seasons.

At-Taubah – 9:37 Arabic إِنَّمَا ٱلنَّسِىٓءُ زِيَادَةٌ فِى ٱلۡكُفۡرِۖ يُضَلُّ بِهِ ٱلَّذِينَ كَفَرُواْ يُحِلُّونَهُۥ عَامًا وَيُحَرِّمُونَهُۥ عَامًا لِّيُوَاطِـُٔواْ عِدَّةَ مَا حَرَّمَ ٱللَّهُ فَيُحِلُّواْ مَا حَرَّمَ ٱللَّهُۚ زُيِّنَ لَهُمۡ سُوٓءُ أَعۡمَٰلِهِمْۗ وَٱللَّهُ لَا يَهۡدِى ٱلۡقَوۡمَ ٱلۡكَٰفِرِينَ https://youtu.be/gPjv5w4eVBg This video talks about what nasi’ means.
Furthermore surah tawbah is one of the last revelations. How could God allow Ramadan and hajj to be done incorrectly for around 20 years? Unless the ruling was present before
Also of course we should challenge the etymology here. Rabee’ literally means spring. So over time it is not far fetched to extrapolate that people forgot this meaning over time. For example September and October are months seven and eight. But in our calendar they are months nine and ten. So it can’t have tawatur because as we can see here meanings can be lost over time especially when it’s to do with calendars that are not used or paid attention to every day all the time
What is the proof that this change in meaning was deliberate and not just a mistake of early Muslims not being able to intercalate because of the expulsion of Jews from Arabia?
I think it is well known history that quraysh used to intercalate their calendar.
But why should we ignore Quran altogether? the way Quran mentions this fact, makes it obvious that months and their actual order was well known to Quraysh. Even if Umar (rta) initiated an official Hijri calendar, this doesn’t mean he changed the order of months and their actual happening. I honestly cannot comment on the validity of narrative mentioned in the link shared above. Will request Hassan Sahab to give his insight as well.
