Choose a reviewed alarm preset below to open the alarm clock with that time already selected. You can adjust the time, choose and test a sound, then press Set Alarm. Keep the tab open and your device awake until it rings. For any other time, use the main online alarm clock.
Choose the alarm by job
Need more than a preset time? Use a wake-up alarm for mornings, a meeting reminder alarm for calls, a school alarm for classes, or a work alarm for deadlines and breaks.
💡 Tip: Heavy sleeper? Set two alarms apart - For example a 7:00 AM and a 7:30 AM backup.

How to set an alarm in 3 steps
Start with a preset or choose your own time
Preset alarm pages are useful for common wake-up times, work reminders, and short breaks. If the preset is not exact, adjust the hour and minute before you activate it.
- Pick a time. Choose a preset from the lists above (like a 6:00 AM alarm) or set your own.
- Add a label (optional). Name it "Wake up" or "Meeting" so you know what it's for.
- Keep the tab open. Leave Alarm.now open and the alarm will sound at the right time.
Why use an online alarm?
Good for wake-ups, reminders, and timed routines
An online alarm is best when you are already working in a browser and want a clear sound alert. For longer work blocks, pair it with a 25-minute timer or the multi-timer.
- Always with you: works on any computer or phone with a browser.
- Loud and clear: plays a sound and shows a pop-up when time is up.
- More than wake-ups: great for reminders, breaks, cooking and study.
- Pairs with our other tools: try the 10-minute timer or stopwatch too.
