The time remaining until 3:00 depends on the current time. For example, if it is around 12:48 PM UTC now (based on the system time), there are roughly 2 hours and 12 minutes left until 3:00 PM. The exact remaining time can be found by subtracting the current time from 3:00 PM, taking into account hours and minutes.
If a precise countdown is needed, tools like time until calculators or countdown timers can provide the exact hours, minutes, and seconds remaining until 3:00 PM at the current moment.
