Second Timers
Short and precise. Second timers are made for the quick, repeatable moments - Plank holds, espresso shots, breathing resets, interval training and game turns. Pick a duration below and the countdown opens ready to run with a large display and selectable finish sound.
Tip: press Space to start or pause, R to reset, F for full screen.
How to Choose Between Second Timers
Second timers cover 1 to 300 seconds for short tasks such as planks, breathing, hand-washing and game turns.
Some things only take a handful of seconds. A plank hold. A deep breath. Rinsing your hands. You don't need a long countdown for those - You need something fast and exact. That's what a second timer is for.
Set any length from 1 to 300 seconds and hit start. Want to skip the setup? Jump straight to a 30-second timer or grab our interval timer for back-to-back rounds.
Why short timers work so well
Seconds are the sweet spot for anything you repeat or need to nail on the dot. Think fast bursts of effort with a clear finish line.
- Exercise: plank holds, wall sits, sprints, and rest gaps between sets.
- Cooking: a 25-second espresso shot, blanching veggies, or resting a searing pan.
- Health: a full 20-second hand-wash or a slow box-breathing cycle.
- Play: game turns, quiz buzzers, and reaction drills that keep everyone honest.
For high-intensity training built on short work-to-rest splits, our Tabata timer runs the classic 20-on, 10-off rhythm for you.

Tip: Keep the tab open and test the alarm; hidden or locked devices may suppress browser audio.
Tip: Chain short timers back-to-back for HIIT rounds instead of resetting each one.
Tip: Say the seconds out loud with kids during teeth-brushing or clean-up to make the countdown fun.
Tip: For breathing, match your inhale and exhale to even splits like 4 seconds in, 4 seconds out.

About second timers
Second timers are for moments where precision matters more than planning: exercise holds, work-and-rest intervals, hand washing, reaction drills and short classroom cues. Pick the exact number rather than rounding to a minute, especially when the timer will repeat.
For repeated training, turn on Loop or use the interval timer. For a one-off task that needs more setup, a minute timer usually gives you a more practical finish line.
