That's very cute, lol.

Thinking about Ramadan, is it a coincidence that it's around the same time as the day of atonement, which came about because of this:

After the Ten Commandments were given to Israel on Pentecost, Moses ascended Mt. Sinai and remained there 40 days to receive the Tablets. He descended on the 17th of Tammuz and broke the Tablets because the people worshipped the Golden Calf. For forty days Moses set up his tent beyond the camp of Israel, and the people mourned. On the 1st of Elul (sixth month), Moses ascended the mountain to receive the Second Tablets. During this period the Hebrews fasted daily from sunrise to sunset. On the 40th day they fasted from sunset to sunset. This was Tishri 10. On the morning of the 10th, the Hebrews wept when Moses came down with the tablets, and he wept when he beheld their repentance. Then God said, "Your repentance is accepted, and this day will remain the Day of Atonement throughout all generations
I also read somewhere, now I can't find it, that mohammed did observe the day of atonement but then he changed it later to Ramadan? Would this be right? I'm learning that there are a lot of similarities between the religions.

Oh I think I might have just found the answer, looked it up and this is what it said:
Many are aware that Muslims devote an entire month--that of Ramadan--to a fast that extends through the daylight hours, coinciding with the revelation of the Koran, the sacred scripture of Islam. The fast is known as the sawm (identical to the Hebrew word for a fast, tzom). Less widely known is the fact that the institution of Ramadan took the place of an earlier practice, a single-day (24 hour) fast known in Arabic as the Ashura.

Islamic tradition bases this custom on a reference in the Koran (2:183-187) to keeping "the fast as it was prescribed for those before you". Muslim tradition explains that "those before you" were the Jews, and that Muhammad in this passage was commanding that his followers adopt the Jewish custom of fasting on the Day of Atonement.
The Arabic word Ashura is none other than the Hebrew word Asor, the tenth, the term used in the Bible (Leviticus 16:29, etc.) to designate the date of the holiday (the tenth day of the seventh month).
The origin of this precept is described in the Muslim "oral tradition" (Hadith) as collected by the noted 9th century authority, Al-Bukhari:
When the Prophet came to al-Madinah he found that the Jews observed the fast of Ashura. He enquired about this and was told that it was the day on which God had delivered the Children of Israel from the enemy and Moses used to keep a fast on it as an expression of gratitude to the Almighty. The Prophet thereupon remarked that "Moses has a greater claim upon me than upon you," and he fasted on that day and instructed his followers to do the same.
