Time sums, What time after? chosen. From 3:50 PM, Add 20 minutes, with quick buttons 5 min, 10 min, 15 min and more. The answer: 4:10 pm, 20 minutes after 3:50 pm. — What time after?

How long until?

From is the time now.
Tap Until and set a time, for example 3:30 pm.
The answer shows at the bottom: 1 hour 20 minutes.

What time after?

From is the time now.
Under Add, tap an amount like 15 min, or type the hours and minutes.
The answer shows at the bottom: 4:10 pm.

To start from another time, tap the From box and change it. Now puts it back to the time now.
A time earlier than From is tomorrow's: the answer says tomorrow.
The round ✕ clears everything. Put it back brings it back.
Next time, From starts at the time now again.

💡 Try it with a real plan: "The bus comes at 4:15. How long until then?" Then look at a clock together.
