Ramadan is not just a month where you don't eat from dawn to sunset. Looking at it that way would be very superficial and would lead you to some wrong conclusions. Ramadan is the month in which the Qur'an was initially revealed. This is the month in which the great Angel Gabriel would come and review the Qur'an with Prophet Muhammad (pbuh). This is the month where the gates of Heaven are flung wide open and the gates of Hell are shut tight. This is the month where all the devils (shaytaan) are shackled so that they can not affect us.
It's a month of reflection, extra prayer and a month in which we purify ourselves and recharge our spiritual batteries for the coming year. Those who observe Ramadan properly often find that their imaan (faith) levels fly extremely high and that they become more tolerant, more patient and more calm.
A lot of people, including Muslims, get confused that Ramadan is only about not eating during the day time and then getting to eat really good food in the night when breaking your fast. But I would argue that what is more important than that is the spiritual side of things. Ramadan is about perfecing your character and being the best Muslim you can be. The fast is not just a physical fast of staying away from food but also a spiritual fast. It's a fast of your entire body. We must watch what we say about other people behind their backs, watch what we see with our eyes, watch where we go with our feet and watch what we do with our hands. A fast of our entire body means to keep our entire body pure of all the sinful things that we may be doing during the year. It's a time to rid ourselves of all of those things and incorporate perfect character into ourselves...or atleast try to.
Most importantly, it's a time to seek forgiveness from God. God is the most forgiving being in all the world. It comes in hadeeth that when God created mercy, he split it up into 99 parts. He gave one of those parts to the world. That is why the mother bears her young in extreme pain, then suckles him for some years and then provides for him throughout the rest of his life. It's why even when she hasn't slept for days, she will get up to give him a glass of water in the middle of the night. The rest of the 98 parts, God kept for Himself. So if God is so merciful, then what better time to ask for forgiveness than Ramadan?
Sorry for a kind of long explanation, but its not something that can be explained in a few sentances. But as you can see, Ramadan is a greatly spiritual month for Muslims. I hope that cleared up any questions you had about it
Also, I think Ramadan starts at the same time as Rosh Hashana so Happy Rosh Hashana to everyone out there of the Jewish faith
