About the Time Until Calculator
The Time Until Calculator answers a simple but frequently asked question: how long until a specific time? Whether you are counting down to the end of the work day at 5:00 PM, a lunch break at 12:00 PM, or an early morning meeting at 9:00 AM, this tool gives you a live countdown in hours, minutes, and seconds.
Each countdown page also shows the target time in 24-hour format, military time notation, and the percentage of the day that will have elapsed at that point. If the target time has already passed today, the countdown automatically switches to tomorrow — so the result is always useful.

How It Works
The Time Until Calculator computes the exact difference between the current time and your target time. It shows hours, minutes, and seconds remaining in a live countdown.
If the target time has already passed today, the calculator will show the countdown to that time tomorrow. All calculations use your device's local time and update in real time.
