In 2027, the first sighting of the crescent moon that marks the end of Ramadan is expected around 10 November, placing Hari Raya (Eid al‑Fitr) on 11 November for most of the United States. The date aligns with the 1st of Shawwal in the Hijri calendar, a month that shifts roughly 10‑11 days earlier each solar year because the Islamic calendar is lunar‑based and lacks leap‑year corrections.
The timing matters for workplaces, schools, and community organizers across the country. Federal and state employers typically observe the holiday as a paid leave day when the date falls on a weekday, while schools may adjust academic calendars. Understanding the 2027 schedule helps planners accommodate diverse observances and coordinate inter‑faith events that now often feature Hari Raya as a cultural touchstone in American society.
