Clock With Seconds
See a large live clock with seconds visible by default, plus 12/24-hour mode, date, copy, and fullscreen controls.
How this clock with seconds works
This page shows the current time from your browser and device clock with seconds included in the main display. It is designed for quick checks, room displays, and fullscreen use when a minute-only clock is not detailed enough.
The clock updates to the next second boundary while seconds are visible. Browser scheduling, device clock settings, inactive tabs, and display refresh rate can affect what you see, so this is not an official or guaranteed time source.
When seconds are useful
A live clock with seconds helps with shared room displays, classroom timing, meeting rooms, live stream timing, minute rollover checks, and second-screen clocks. Hide seconds when you want a quieter display.
For a general digital clock, use the digital clock. For a room-sized display, use the full screen clock. For smaller fractions of a second, use the clock with milliseconds. For a clock face with a visible second hand, open the analog clock with second hand. For a smooth analog display, try the smooth second hand clock.

Clock with seconds FAQ
Does this clock show seconds by default?
Yes. The main display includes live seconds by default, with a toggle to hide them when you want a quieter clock.
Is this an official time source?
No. The clock formats the time from your browser and device clock, so device settings and drift can affect what you see.
Can I use it fullscreen?
Yes. The fullscreen view keeps the current time large and readable, and no ad placeholders are rendered inside the fullscreen clock frame.
