30 Second Timer

Press Start and this half-minute countdown runs from 00:30 to zero, then plays a four-tone alarm. A progress bar fills as the seconds pass and the tab title shows how many are left. It is free and runs in your browser, so nothing you type is sent anywhere.

How to use the 30 second timer

The page opens already set to thirty seconds, so the clock reads 00:30. Because the Quick start menu starts at one minute, it shows Custom time, and the three boxes below it hold the real setting.

  1. Look at Hours, Minutes and Seconds. They read 0, 0 and 30. If a round should last 45 seconds instead, type 45 in Seconds and the clock follows.
  2. Type a Label (optional) such as Round 1 or Question 4. The label sits above the digits and is repeated in the message at zero, which helps when you run many rounds in a row.
  3. Decide on Play a sound when time is up. It is on at first, and a sound is useful when players are watching each other, not the screen.
  4. Press Start and the digits count down. Pause freezes the clock, and the same button becomes Resume.
  5. Press Reset to go back to 00:30. Use Full screen when a class, a team or a family should be able to read the time from across the room.

You can also press Space to start or pause, and R to reset while the timer is stopped. When the alarm has finished, one more press of Space begins a new thirty seconds.

Speed rounds, quiz questions and one-line pitches

Half a minute is long enough to answer a question and short enough that nobody can ramble. It is a popular limit for games and for practice talks.

Quiz questions. Give each team 30 seconds to agree an answer. A quiz of 10 questions needs 10 x 30 = 300 seconds, which is 5 minutes of thinking time, plus the seconds you spend reading each question aloud. If you want to choose who answers next, the wheel spinner picks a name at random.

Speed rounds. Ask players to name as many animals, countries or kitchen tools as they can before the alarm. One person keeps score while the others count. The short limit keeps the pace lively, and the full screen clock makes the deadline fair to everyone.

A one-line pitch. Many people speak at roughly 130 words per minute, which is about 65 words in half a minute. A pitch of two sentences and around 50 words therefore fits comfortably, and it leaves a few seconds for a pause. Paste your draft into the word counter to see its length, then say it aloud against the clock. Speaking rates differ between people and between languages, so treat 130 as a starting point and adjust it to your own pace.

Here is how the clock reads at the end of each stage in a short practice talk:

Opening line500:25
The one idea1500:10
Closing ask1000:00

Repeating the practice a few times and trimming words each time is usually more helpful than adding new ones.

Work and rest blocks, stretches and limits

Thirty seconds is a common unit in home exercise programs, where a set of 30 seconds of effort is followed by 30 seconds of rest. This timer will not alternate for you. It counts one block, beeps, and waits, so the pattern is: press Start, work until the beep, press Space, rest until the next beep, and repeat. Eight work blocks with eight rests make 16 blocks, which is 480 seconds or 8 minutes, plus the second or two it takes to press the key each time. Choose a pace that suits your fitness, and stop if you feel unwell.

A held stretch is another fit. Holding for around 30 seconds is a figure often mentioned in general fitness guidance. Ease out of any stretch that hurts, and take advice from a qualified professional if you have an injury or a medical condition. This page is a clock, not a coach.

  • Labels change the message. Editing the label between rounds while the clock is stopped lets you name each move, for example Squats or Plank.
  • The alarm is brief. It lasts a little over a second, so keep the volume up when you are across the room.
  • No automatic repeat. There is no loop, no second timer and no saved routine, and a closed tab ends the count.

For shorter prompts, use the 10 second timer. When a round needs a full 60 seconds, the 1 minute timer is the next step, and the minutes to seconds converter turns longer times into seconds for the Seconds box.

Quick answers

Frequently asked questions

The questions people ask most, answered in plain words.

How many words can I say in 30 seconds?

At a typical speaking pace of about 130 words per minute, you can say roughly 65 words in 30 seconds. Nervous speakers often go faster and careful speakers slower, so time yourself once with the countdown and adjust. A short script of 50 to 60 words is a safe target.

Can I run a 30 seconds on, 30 seconds off workout?

Yes, by hand. The timer counts one block of 30 seconds and beeps. Press Space to start the rest, press it again for the next work block, and keep going. It has no automatic interval mode, so you must press the key each time. Choose effort levels that suit your health.

Why does the menu say Custom time instead of 30 seconds?

The Quick start menu begins at 1 minute, so it has nothing for 30 seconds. It reads Custom time while the Seconds box holds 30 and the clock shows 00:30. The countdown is set correctly, and you can change the number in the box at any time before pressing Start.

Will the timer keep time if I switch tabs?

Yes. It compares the finish time with your device clock, so the figure is right when you come back, and the tab title shows the time left. The beep may arrive a moment late in a hidden tab, and closing the tab stops the count, so keep it open.

Is half a minute the same as 0.5 minutes?

Yes. Thirty seconds is 0.5 of a minute, since 30 divided by 60 is 0.5, and it is also 30,000 milliseconds. Two of these blocks make one minute, and ten make five minutes. Use whole seconds in the box, because the timer does not take decimal minutes.
