Getting the metro is really a question of leaving the building at the right minute, since the walk to the station is the part that varies from one day to the next. This page counts down to 8:35 am exactly — the moment to head out, the moment to tap in, or the moment something starts at the other end.
The count runs entirely inside the browser, which is why it needs no account, no permission and no connection once the page has loaded. It also means the figure belongs to this tab: close the page and it stops, and opening it again starts the calculation from scratch rather than resuming.
Twelve o'clock is where the 12-hour clock is weakest: 12 am and 12 pm are read the wrong way round often enough to cause real trouble with bookings and deadlines. Writing the same moment as 08:35 removes the problem entirely, because a 24-hour figure only ever points at one instant in the day.
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 8:35 am, not a figure worked out when the page first opened.
What happens once 8:35 am 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 8:35 am arrives?
No. This is a live figure rather than an alarm — nothing sounds, vibrates or notifies at zero. If you need interrupting at 8:35 am, set an alarm alongside it and use this page as the running total.
