How the countdown to 11:30 pm works
The countdown runs to the next time your clock shows 11:30 pm. If it's earlier than 11:30 pm now, that's later today; if it's 11:30 pm or later, it's 11:30 pm tomorrow. The hours, minutes and seconds update every second.
It works out the time on your own device, in your own time zone, so nothing is looked up online and the answer is right wherever you are. If your device's clock is wrong, the countdown will be off by the same amount.

Frequently asked questions
What is 11:30 pm in 24-hour time?
11:30 pm is 23:30 on the 24-hour clock: add 12 to the hour, so 11 pm becomes 23. In military style it's written 2330 hours.
Is it counting to 11:30 pm today or tomorrow?
Today, if your clock hasn't reached 11:30 pm yet. Once it has, the countdown switches to 11:30 pm tomorrow, so it never shows a time that has passed. The line under the clock says which one it is.
Does the countdown use my time zone?
Yes. It reads the clock and time zone on your own device, so 11:30 pm means 11:30 pm where you are. For 11:30 pm in another city's time, use the countdown to a date and pick that time zone.
How many minutes until 11:30 pm?
The answer box shows the total in minutes and in decimal hours as well as hours, minutes and seconds. For example, from 10 pm it is 90 minutes, or 1 hour 30 minutes.
What happens when the clocks change?
The countdown measures real time. On the night the clocks go forward it is an hour shorter than the clock suggests, and on the night they go back an hour longer.
