Happy Eid! Is it on the same date every year, or does it fluctuate?
It's the same date on the Lunar calendar but it fluctuates on the Gregorian calendar, which shifts roughly 11 days earlier each year. Since we follow the Lunar calendar we sometimes get Ramadan during the winter (short days, yay!) and eventually during the summer (long, long days here: sunrise 4:30 a.m. and sunset 7:30 p.m.), that varies how long we have to fast during the Holy month.
