Muslim festivals are timed according to local sightings of various phases of the moon and the dates given above are approximations. During the lunar month of Ramadan that precedes Ramazan Bayram, Muslims fast during the day and feast at night and normal business patterns may be interrupted. Some disruption may continue into Ramazan Bayram itself. Ramazan Bayram and Kurban Bayram may last up to several days, depending on the region.
