Courts and pitches are booked by the hour and the hour begins whether or not you have arrived, with the drive across town being the part that gets underestimated. This page counts down to 9:30 pm exactly, so the decision about when to leave rests on a number rather than on optimism about the traffic.
This is a display rather than an alarm. Nothing rings, buzzes or notifies at the end, and the page will not interrupt whatever else you are doing. If being interrupted is the point, set an alarm as well and treat this page as the running total you can glance at in the meantime.
India runs half an hour off the round numbers, thirty minutes ahead of the Emirates, which catches out anyone arranging a call by counting whole hours. Since the clocks here never shift, the offset to Mumbai is fixed all year — it is the European and American ones that move underneath you.
Common questions
Will it alert me when 9:30 pm arrives?
No. This is a live figure rather than an alarm — nothing sounds, vibrates or notifies at zero. If you need interrupting at 9:30 pm, set an alarm alongside it and use this page as the running total.
Do the clocks change here?
No. The UAE has no daylight saving at all, so the offset stays at UTC+4 in every month. When the gap to Europe or North America shifts, it is their clocks that moved, not yours.
What is 21:30 on a 12-hour clock?
The same instant is 9:30 pm in writing and half past nine at night out loud. Anything from 13:00 onwards loses twelve to give the pm figure, which is the only sum involved in moving between the two.
Does the number update by itself?
Yes. It is recalculated every second from your device's clock, so nothing needs refreshing or restarting. Whatever is on screen is the current gap to 9:30 pm, not a figure worked out when the page first opened.
