Outdoor working hours begin changing during April in practice, and by law shortly afterwards: the midday break rule bans work in direct sun between 12:30 pm and 3 pm from the middle of June to the middle of September. Sites shift to early starts well before the rule bites, and by the end of April 2028 the first shift on most of them is under way before sunrise.
The 30 days of April 2028 carry no holiday fixed to a date. Where Eid Al Adha falls inside the month, four consecutive days come out of the count — and where any of them meet the weekend they are absorbed by it, since UAE law provides no substitute day for a holiday that lands on a rest day.
April 2028 runs to 30 days and opens the second quarter of a year of 366. Eight months remain, five of them hot, and the school year that ends in July restarts in the last week of August, giving the calendar its single longest break.
