No public holiday falls in September in any of the years from 2026 to 2030, fixed or lunar. Together with October and November it forms the longest unbroken run of ordinary working weeks on the UAE calendar, roughly three months without a day off anywhere in the country, ending only with Eid Al Etihad on 2 December.
Leave in September 2027 costs little in every sense except the allowance itself. Nothing competes for the same days, the schools are in session so families are not travelling, and the heat has eased enough that a week spent in the country is no longer a week spent indoors.
September 2027 runs to 30 days and closes the third quarter of a year of 365. One quarter remains, and it carries the entire outdoor season, the national holiday at the start of December and the school winter break at the end of it.
