Prayer Times: the next prayer could be named incorrectly at northern locations

At locations far enough north that the last prayer of the night falls after midnight, which in the summer months includes much of northern Europe, Iceland, Canada and the northern United States, the Prayer Times page could name the wrong upcoming prayer. Just after midnight the page could point to the following morning's Fajr while a prayer was in fact only minutes away, and in the evening the countdown to the last prayer of the night could announce that its time had arrived early and then stop counting down. Separately, for up to an hour after local midnight the page could still show the previous day's Islamic date. The listed prayer times themselves were correct throughout, visitors at other latitudes were unaffected, and no account data was involved. All three have been corrected and the page has been checked against several northern locations.

Timeline

1. resolved

   23:32 UTC

   This incident has been resolved. A related correction was also applied so the Islamic date turns over promptly at local midnight rather than up to an hour later. The early arrival announcement was possible from July 23; the misnamed next prayer applied to northern locations during the summer months and has been present for longer. Visitors at other latitudes were unaffected and no account data was involved.

2. monitoring

   23:24 UTC

   A fix has been implemented and we are monitoring the results. The next prayer and its countdown now follow the correct prayer at every latitude, and rows are no longer marked as completed before they have passed. If the page still behaves as before, reloading it will pick up the fix.

3. identified

   23:18 UTC

   The issue has been identified and a fix is being implemented. At those locations the page could name the following morning's prayer while a prayer was in fact only minutes away, and the countdown to the last prayer of the night could announce its arrival early and then stop counting down.

4. investigating

   23:12 UTC

   We are currently investigating the next-prayer information shown on the Prayer Times page for locations far to the north, where the last prayer of the night can fall after midnight. This came out of a routine review rather than a visitor report. The listed prayer times themselves are correct.
