So apparently I learned something new today. In Turkey today was Eid al-Fitr or as we call it Ramazan Ramazan Bayramı ("Ramadan Feast"), Şeker Bayramı. And for you it's tomorrow and today is just another day of Ramadan with fasting.
Traditionally, it is the day (beginning at sunset) of the first sighting of the crescent moon shortly after sunset. If the moon is not observed immediately after the 29th day of the previous lunar month (either because clouds block its view or because the western sky is still too bright when the moon sets), then it is the following day.
