How to use it
- Type the names of the two teams, and set the Minutes per period and the Periods for your match.
- Choose Clock: count down from the period length, or count up from zero.
- Press Start to run the clock, and +1 or −1 under a team's score to change it.
- Use the keys to score without the mouse, and Next period when the period changes.
Period lengths in the rules
A football match is two halves of 45 minutes, and the interval at half time may not be longer than 15 minutes (IFAB Laws of the Game, Law 7). A basketball game is four quarters of 10 minutes (FIBA Official Basketball Rules 2026, Article 8.1). Set the length and the number of periods for the sport you are watching, or for any other match.
- The clock does not add stoppage time, extra time or the time of an interval. Add those yourself when you use them.
- Sports with other period rules, such as an overtime of a set length, can be followed by changing the period length and the number of periods.
How the clock works
The clock counts down to zero, or up to the length of the period, and then stops by itself. Stopping keeps the time shown; starting again continues from that time. The time is taken from the browser's clock, so a clock that is running stays right even if the tab is in the background.
Example: a football half counted down
A 45-minute half counted down starts at 45:00. After 90 seconds of play the clock shows 43:30, and when the half is over the clock stops itself at 00:00 and the page says the period is over.
Frequently asked questions
Does the scoreboard store the score?
No. Nothing is stored or sent to us. When you leave or reload the page, the scores and the clock start again from zero.
Can I use it on a phone or on a big screen?
Yes. Use Full screen to fill the screen. On a narrow screen the panels wrap onto separate rows, so the page still works on a phone.
Why do the keys not work when I type a team name?
The keys are ignored while a text box, a number box or a list has the focus, so you can type a name. Click on the page away from the boxes to give the keys back to the scoreboard.
What is the difference between counting up and counting down?
A countdown shows the time left in the period and stops at zero. A count-up shows the time played and stops at the length of the period, which suits a match where you add the stoppage time yourself.
Does the clock stay right when I switch tabs?
Yes. The clock is worked out from the browser's time, not counted in steps, so it stays right. Some browsers slow down the page in a background tab, but the time shown still matches the real time.
