A live clock with seconds is a real-time digital clock that displays hours, minutes, and seconds—updating every second without a page refresh. Unlike a standard clock that only shows hours and minutes, the seconds display lets you see time moving in real time. This is useful for presentations, live streams, classrooms, time-sensitive tasks, or simply knowing the exact time at a glance.
Our clock runs entirely in your browser. It reads your device's system clock and displays the time immediately without waiting for a remote time server. If you switch timezones, the clock updates the time, date, and timezone label together.
This live clock with seconds also shows the full date below the time—weekday, month, day, and year. If you only need the time, choose "Hide Date" and the line disappears. The date follows the selected timezone, so choosing New York or London also updates the day correctly across midnight. This makes the page useful as a desktop clock, a meeting reference, or a wall display where both time and date need to be visible at a glance.
Many device clocks hide seconds, but there are situations where seeing each tick matters:
Open this page and the clock starts immediately—no setup, download, or signup required. Seconds appear beside the hours and minutes, with a subtle accent and tick response that makes each change easy to notice. Milliseconds remain optional when a more precise readout is useful.
You can:
For tasks that need sub-second precision, you can enable milliseconds. The extra digits appear after the seconds and update in real time, useful for checking network latency, testing sync, or measuring short intervals by eye. Milliseconds are off by default to keep the clock calm and readable, and your preference is saved for the next visit.
Our main live clock page also shows seconds and lets you hide them. This dedicated page gives seconds stronger visual emphasis and a subtle response on every tick, making it better suited to people who specifically searched for a clock with visible seconds. Both pages share the same timezone, theme, and template preferences, so a choice made on one page carries over to the other.
Choose “Full Screen” to open a clock designed to fill your monitor. It is useful for classrooms, conference rooms, studios, or shared displays where the current time needs to be visible from across the room. Your seconds, milliseconds, theme, and template preferences carry into full screen mode. Move the pointer to reveal its controls, then use Exit or press Escape to leave browser full screen.
Four clock templates are available:
Prefer a traditional clock face? Switch to the Analog template to see this live clock as a round dial with a sweeping second hand. The hand updates every second and matches the same live time as the digital display. Use the Analog view for classrooms, studios, or any setup where a wall-clock look feels more natural. Switch back to Digital, Mono, or Classic anytime; the choice is saved with your theme.
You don't need an app, a browser extension, or an account to use this live clock with seconds. Open the page and the time appears immediately—there is nothing to install and nothing to configure. Because the clock runs on your device's system clock, it also works without sending your data to any server. For a cleaner view, expand to full screen; for a themed display, open the aesthetic themes page.
Color themes include Default White, Paper Minimal, Amber Terminal, Vaporwave, and Green Phosphor. The theme controls the clock palette and background, while the template controls the numerals and animation. They work independently, so you can combine any template with any theme.
If you want more than a plain digital readout, our aesthetic clock themes let you switch between vaporwave, matrix, amber, paper, and other full-screen looks. Combine any theme with the seconds display here, then keep the page open as a desktop background, a stream overlay, or a focused work timer. The theme, template, and seconds settings are remembered between pages.
After the page has loaded, the clock can continue running in the open tab because it uses your device's system clock. The site is not an offline-first app, so refreshing or reopening it without a connection may fail if the page assets are not cached.
The clock displays the time reported by your device. Most modern computers and phones synchronize with network time services, but an incorrect device clock or timezone will also be reflected here.
We do not currently offer a dedicated embed widget or public API. A standard iframe may work where your website platform permits external pages, but opening the clock in a separate window or linking to the focused full screen page is the supported option.
Yes. Auto detection follows your device's timezone, while a manually selected city uses that timezone's daylight saving rules through your browser. If the device timezone is wrong, Auto detection will reflect that error.
Both pages display seconds by default and use the same clock engine, templates, themes, and saved preferences. This page is designed specifically around seconds: they receive stronger visual emphasis and a subtle response on every tick.
Yes. Choose Show Milliseconds to add three lighter digits after the seconds. Milliseconds are off by default, update from your device clock in real time, and remain enabled across refreshes, full screen mode, and template changes until you turn them off.
Yes. Choose the Analog template to show a round clock face with hour, minute, and second hands. It uses the same timezone and theme as the digital clock, works in full screen, and stays selected when you refresh or move between pages.
