Digital Clock
Big, readable local time. Toggle seconds and 12/24-hour, go fullscreen, and copy the current time.
How it works
Digital Clock is a big on-screen clock that shows your current local time in a clean, readable format. It is built for practical moments: putting a clock on a second monitor, projecting a clock in a room, keeping time visible during meetings, or quickly copying a timestamp into notes.
You control three things: whether seconds are shown, whether the time is in 12-hour or 24-hour format, and whether the display is normal or fullscreen. The clock also has a Copy action that gives you a paste-ready snapshot including time, timezone, date, and an ISO timestamp so the copied value is unambiguous.
This digital clock is intentionally focused on hours, minutes, and optional seconds. It does not show milliseconds. If you need a live clock with milliseconds for frame timing, cue checks, or precise-looking screen recordings, use Atomic Clock instead.
The key point: this page displays your device’s time and detected timezone. It does not fetch “internet time” on its own. If your laptop clock is off by two minutes, this page will be off by two minutes. If you need UTC as a shared reference, use UTC Clock. If you need a millisecond display, use Atomic Clock.
- 1) Set your display: toggle Seconds on/off and choose 12/24-hour.
- 2) Press F to go fullscreen when you need a room-readable clock. Exit with Esc.
- 3) Press C or click Copy to copy a clean timestamp.
- 4) If you want quick toggles without hunting controls: S toggles seconds,1/2 switches 12/24-hour.
People often paste time into places where context gets lost. Copy includes the timezone and date (plus an ISO timestamp) so “3:15 PM” does not become confusing later. The copied value is meant to survive forwarding, screenshots, and handoffs.
- Confirm your device timezone is correct (especially after travel or VPN changes).
- If seconds matter, turn seconds on so you can see exact boundaries.
- If you are coordinating across time zones, keep a UTC Clock tab nearby for a neutral reference.
- If shortcuts do nothing, click the clock card once to focus it. Shortcuts do not fire while typing in a form field.
What you can do on this page
This clock is intentionally simple, but it is built for real workflows. Seconds mode is for precision. No-seconds mode is for calm readability. 24-hour mode is for environments where “13:05” is clearer than “1:05 PM”. Fullscreen mode is for distance viewing. Copy is for moving time into messages, notes, or logs without losing context.
The display also shows your timezone label (when available). That matters when you are in a shared room or on a call with people in different places. If the timezone label can’t be detected, it falls back to “Local” and the time still displays normally.
Scenarios with examples (real outputs you will see)
The scenarios below are written to match what you will actually do with this page. Each includes concrete example outputs so you can recognize the behavior immediately.
Fullscreen exists so the clock stays readable at a distance. Shortcuts keep it fast: F fullscreen, C copy, S toggle seconds, and 1/2 12/24-hour. If shortcuts do nothing, click the clock card once so it has focus.
If you need multiple cities, time conversion, UTC, milliseconds, or a different display style, these are better matches.
Technical details (time source, update timing, copy, fullscreen)Notes that matter if you rely on seconds, timestamps, or screen sharing▼
The clock reads the current time from your browser’s Date object and formats it using Intl.DateTimeFormat when available. The timezone label uses Intl.DateTimeFormat().resolvedOptions().timeZone when the browser supports it.
When seconds are enabled, updates are scheduled on the next second boundary to reduce drift. When seconds are hidden, the clock updates close to the start of each minute to avoid unnecessary re-renders.
Copy includes the currently displayed time (respecting 12/24-hour and seconds), the timezone label, the formatted date line, and the ISO timestamp from toISOString() for a machine-readable reference.
Fullscreen uses the browser Fullscreen API and updates state on fullscreenchange. Some browsers require a user gesture (click/tap) to enter fullscreen. Clipboard access can also be restricted by browser policy and is most reliable after a user action.
Need milliseconds as the main focus? Open the clock with milliseconds. Need a page optimized for room display? Use the full screen clock. Need the biggest room-readable digits? Open the big digital clock. Need a dedicated 24-hour display? Use the 24 hour clock. Prefer AM/PM as the main view? Use the 12 hour clock. Need seconds called out directly? Open the clock with seconds. Prefer an analog face with continuous motion? Try the smooth second hand clock.
Keyboard shortcuts
Click the clock card once, then use the keyboard to control it. Shortcuts won’t trigger while you’re typing in an input, select, textarea, or editable field.
| Key | Action |
|---|---|
| F | Toggle fullscreen |
| C | Copy the current time |
| S | Toggle seconds on/off |
| 1 | Switch to 12-hour time |
| 2 | Switch to 24-hour time |
| Esc | Exit fullscreen |
Common scenarios
Use this page as a big, readable local clock. Toggle seconds and 12/24-hour time, go fullscreen for distance viewing, and copy the current time when you need a quick timestamp.

Details and shortcuts▼
F fullscreen · C copy · S toggle seconds · 1 12-hour · 2 24-hour · Esc exit fullscreen.
If shortcuts don’t work, click/tap the clock once so it has focus.
Copy includes your displayed time, your timezone, the date, and an ISO timestamp for unambiguous pasting into logs or notes.
The clock shows your device’s local time and timezone. If your device time is incorrect, the display will be incorrect too.
Some browsers require a user gesture to enter fullscreen. In fullscreen, clicking/tapping the time copies it.
