The fast breaks at sunset, and sunset shifts by a minute or so each day, so the time that applied last week is not the time tonight. If 7:44 pm is this evening's figure, this page counts down to it exactly — hours, minutes and seconds — which is what everyone in the kitchen actually wants to know.
Nothing here is stored, sent or remembered. The page works out one number from your device's clock and draws it, and that is the whole of what it does. Closing the tab leaves nothing behind, and there is no history of times you have looked up sitting anywhere afterwards.
Plenty of phones and dashboards default to a 24-hour display regardless of how people around them actually speak, so 19:44 may well be the figure staring back at you while 7:44 pm is what anyone would say out loud. Neither form is more correct; they are just aimed at different readers.
Common questions
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 7:44 pm, not a figure worked out when the page first opened.
What happens once 7:44 pm has passed for today?
The count rolls over and carries on towards the same time tomorrow. That happens on its own at the moment the time passes — the page does not need reloading and there is nothing to reset by hand.
Which clock does the countdown use?
Your own. It reads the local time and time zone from the device in front of you, which in the Emirates means Gulf Standard Time, UTC+4. Travel and the count follows whatever the device picks up.
Will it alert me when 7:44 pm arrives?
No. This is a live figure rather than an alarm — nothing sounds, vibrates or notifies at zero. If you need interrupting at 7:44 pm, set an alarm alongside it and use this page as the running total.
