Where I reside, the Islamic Committee decides when Eid al Fitr will be. This Sunday after Magrib, they will make an announcement as to whether or not Eid will be on Monday (Moon spotted Sunday night) or Tuesday (Moon not spotted Sunday night).
I remember when I was small my family was fasting on the 30th day of Ramadan, and we saw our neighbours celebrating Eid with a bunch of family over ^o)
Inshallah we don't forget about the last few days of Ramadan and continue to make steady fast and prayers.
