Wake up alarm does not go off when set after midnight

Hi Bo9723,

Thanks for connecting with Apple Support Communities.

You can set alarms for any time of day and have them repeat on one or more days of the week, when using the Clock app, using these steps:

"Set a regular alarm

You can set regular alarms for any time, including one for the time you want to wake up. A regular alarm is unrelated to any sleep schedule.

1. Tap Alarm, then tap .
2. Set the time, then choose any of the following options:

• Repeat: Choose the days of the week.
• Label: Give the alarm a name, like “Water the plants.”
• Sound: Choose a vibration, song, or ringtone.
• Snooze: Give yourself a few more minutes of sleep.

3. Tap Save.

To change the alarm, tap Edit at the top left, then tap the alarm time.

If the Clock app is not working as expected, the following steps may be able to help resolve the issue:

• Restart your iPhone. This may seem like a simple step to take but can often resolve several issues.

1. "Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

• Update your iPhone. Completing this step ensures that your device has the latest fixes. (Secure your data with a backup)

We hope this helps.

Take care.
