Hi. Today is not the first day of the new year here. It is the first day of an islamic holiday called " Eid Al-Fitr. It is a holiday coming directly after fasting the whole month of Ramadan. Muslims celebrate completing fasting the holy month " Ramadan " at that " Eid ".It is as a prize from Allah " the name of God in Islam" to those who did their best worshipping Him by fasting and praying and practicing variuos kinds of worshipping during Ramadan. Muslims celebrate it by exchange gifts and visits among themselves congratulating each other saying " Eid Mubarak " which means " wish you blessed Eid " Hope it is clear for you now. Thanks for your question .

Not in the world. But in the universe! WOW :) In turkish countries its named also Uraza bairam. It's the best holiday!
