Who found out what the real calendar should be?

[w3bcrowf3r]

Atm we Arabs have a luni only calendar. I believe it should be a luni-solar calendar.

I am trying to figure out what it would look like. If i figured it out, i want to use it for myself.

Also a question i have. When should we start counting the four holy months. All we know is that they follow each other up. My logical conclusion is that we start with Ramadan, and i will stick with this decision to make it practical for myself. This would make the last 4 months be the holy months.
Every interpretation that is more truthful to the one that i have now is welcome.

I think a lot of people who try to follow the Quran don't ask these questions. They are complex though. Especially if you want to decipher the timings of the luni-solar calendar (when does a month start and end, and when does a year start and end etc.).

NOTE: Please reply only if you are doing any research about this topic. Lets keep it clean. Lets not respond just for the sake of responding.
