I see that many people is just to deep in love with their sun-god to listen.
12 lunar months/full moons/shahars, or wathever you want to call them, are a year.
God is saying "The (iddat) number of shohoor is twelve shahrs"
God is not saying "One year is twelve shahrs."
If he said "One year is twelve shahrs"
he would be unable to answer this question:
According to that year system you mention, what season was Muhammad born?
Neither would he be able to anwser
What particular part of the year system is the hunting restriction mentioned in the Quran as follows?
O you who believe, God will test you with some of the game for hunting coming within reach of your hands and your spears... (5:94)
O you who believe, do not kill any game while you are restricted... (5:95)
Remember that God is able to do anything he wants
but still he is unable to answer these questions.
The decrepancy is caused by the lie that in 9:36 God is saying "Twelve shahrs are a year."
No. Twelve shahrs are NOT a year but a series of shohoor, in other words, they are the wholeness of the series.
If you decrease the number to, say, eleven, the wholenes disappears, the concept of time, seasons disappears.
If you do that, your your sin of rejecting God's order doubles (at-Taubah 37): إِنَّمَا النَّسِيءُ زِيَادَةٌ فِي الْكُفْرِ
which is the very sin the people have committed in making up the pure lunar year.
