Site how long until 4:00 a.m. — active?

This page counts down to the next 4:00 AM shown by your device. Set the clock to UTC+8. There is no daylight saving, but a manually selected zone can still move the finish hour.

4:00 AM falls in a very late or pre-dawn hour, when public transport is limited. Set the sound above the hum of an electric fan or air conditioner, and use vibration if the phone will be in a pocket on a jeepney, bus, train, or ferry. Keep the screen within reach only when it is safe to respond.

Treat the alert as a cue for the first action: leave home, take medicine, log in, collect a child, or begin cooking rice. Allow extra travel time during rush hour and heavy rain. The timer cannot detect flooded streets, a transport queue, a class suspension, or a delayed departure.
