About the Time.how Online Alarm
Welcome to Time.how, your reliable source for precision timekeeping tools. Our online alarm clock is designed to be simple, secure, and effective directly within your browser.
How to Use
- Select Time: Use the large time picker dropdowns to set the hour, minute, and AM/PM.
- Customize: Give your alarm a label (like "Meeting" or "Nap") and choose a sound that suits your need.
- Activate: Click "Set Alarm". The interface will switch to a confirmation view showing exactly when the alarm will ring.
Features & Tips
- Browser-Based: No downloads required. This tool works entirely in your web browser.
- Persistent: If you accidentally close the tab and reopen it immediately, the alarm state is saved (as long as the time hasn't passed).
- Keep It Open: For the alarm to sound, this browser tab must remain open. It can be in the background, but the computer should not go to sleep.
Frequently Asked Questions
Does this work if I close the browser?
No. Web-based alarms require the browser tab to be active or running in the background to track time and play sound.
Is it accurate?
Yes. Time.how synchronizes with your device's system clock to ensure the alarm triggers precisely at the second you selected.
