The Alarms & Clock app in Windows is a simple, built-in tool that helps you set alarms, use a timer, track stopwatches, and view world clocks. It’s useful for staying on schedule, managing time, or waking up on time. Here’s how to use each feature effectively.

1. Setting an Alarm

The Alarms tab lets you create one-time or recurring alerts.

• Open the Alarms & Clock app (search for it in the Start menu).
• Click on Alarm in the left sidebar.
• Click the (Add) button to create a new alarm.
• Set the time using the clock or number fields.
• Give the alarm a name (e.g., “Wake Up”).
• Choose which days it repeats (e.g., weekdays only).
• Pick a sound from the alert list.
• Toggle on Snooze if you want a recurring reminder every few minutes after the alarm goes off.
• Click Save.

You can edit or delete alarms later by clicking the three dots next to them.

Tip: Alarms will still work if your PC is asleep, but not if it's shut down. Make sure your device stays on.

2. Using the Timer

The Timer feature counts down from a set time and alerts you when it finishes.

• Go to the Timer tab.
• Enter how long you want to count down (e.g., 10 minutes for cooking).
• Add a label like “Pasta” or “Study Break.”
• Choose a sound for when the timer ends.
• Click Start.

You can pause, reset, or delete the timer while it’s running. Multiple timers can be saved and started later.

Useful for: Cooking, focused work sessions (like Pomodoro), or reminding yourself to take breaks.

3. Running a Stopwatch

Use the Stopwatch to track elapsed time.

• Switch to the Stopwatch tab.
• Click Start to begin timing.
• Use Lap to record split times (great for workouts).
• Click Stop and then Reset to clear.

The laps are saved and displayed below the timer while running.

Good for: Tracking workouts, timing events, or measuring how long tasks take.

4. Adding World Clocks

Check the current time in other cities or time zones.

• Click the World clock tab.
• Click Add a new city.
• Search for a city (e.g., Tokyo, London) and select it.
• The time will appear with the city name and local time.

You can add multiple cities and remove them by clicking the trash icon.

Handy when: Scheduling calls with people in other countries or tracking travel destinations.

The app runs in the background and sends notifications when alarms or timers go off—even if the app is closed. However, it doesn’t run on the lock screen unless you’ve enabled notifications to show there.

Basically, it’s a lightweight but practical tool for everyday time management—no downloads needed.
