School dinner sits at a fixed point in the timetable and is watched more closely than almost anything else in the day. If 1:50 pm is that point, or the end of it, this page gives the precise time remaining rather than the rough estimate a classroom clock on the wall tends to invite.
Nothing is downloaded, nothing is registered, and nothing is left on the device afterwards. The whole count runs inside the page you already have open. Closing it costs nothing at all, and opening it again later simply shows the accurate gap to 1:50 pm as it stands at that moment.
Twelve o'clock is where the 12-hour clock is at its weakest, since 12 am and 12 pm are read the wrong way round often enough to cause real trouble. Writing a time as 13:50 removes the problem outright, because a 24-hour figure only ever points at one moment in the day.
Common questions
What is 13:50 in the 12-hour clock?
That is 1:50 pm, or ten to two in the afternoon if you are saying it aloud. From 13:00 onwards, subtracting twelve gives the pm figure — the same moment written three different ways.
Does the number update by itself?
Yes. It recalculates every second from your device's clock, so there is nothing to refresh or restart. Whatever is on screen is the current gap to the target time, not a figure worked out when the page first loaded.
What happens if 1:50 pm has already gone for today?
The count simply carries on towards the next occurrence, which is tomorrow. That rollover happens on its own — the page does not need reloading and there is nothing to reset by hand.
Which clock does it use?
Your own. It reads the local time and time zone from the device you are looking at, so the figure reflects where you actually are rather than a fixed zone written into the page.
