Countdown Timer
A countdown timer shows the time remaining until a chosen date and time, broken into days, hours, minutes, and seconds, updating once per second in real time. Starting the countdown only after the page loads in the browser, rather than baking in a fixed now at build time, is what makes the tool correct for every visitor regardless of when they load the page, while still letting search engines see the full page structure and instructions in the initial HTML.
Enter a valid target date and time. The countdown starts once the page finishes loading.
How it works
- Enter the target date and time.
- The countdown starts automatically once the page finishes loading and updates every second.
Formula target time − current time, broken into days/hours/minutes/seconds
Frequently asked questions
What time zone is the target date in?
Your browser's local time zone — the same zone your device shows for the date/time picker.
What happens after the target time passes?
The label switches to "Time since" and continues counting up from the target instead of down to it.
Does the countdown run if I leave the tab open overnight?
Yes — as long as the page stays open, it keeps ticking every second.
Why does the timer show a static value before I interact with the page?
The live countdown only starts once the page finishes loading in your browser — search engines see the tool and its instructions, not a frozen "now" from when the page was built.
Can I count down to a recurring event, like every Friday?
No — each countdown targets a single fixed date and time. For a repeating event, re-enter the next occurrence’s date once the current countdown finishes.
