What the result means
The Saudi Ministry of Education announces the academic calendar in multi-year blocks (currently 1447-1450 AH / 2025-2028), with a specific Gregorian date for each academic year's end-of-year vacation. This differs from every other countdown on this site (Ramadan, the two Eids, National Day), which are calculated automatically with no human maintenance. The summer-vacation countdown, by contrast, shares the same data table used by the school-year-start countdown, and is manually reviewed whenever the Ministry issues a new official calendar.
Recommendation
Check the official Ministry of Education announcement directly to confirm the exact date close to each school year's end, especially for calculated years (1449 and 1450 AH) for which no direct Gregorian date had been issued by the Ministry as of this page's last review.
