15 Second Timer

Fifteen seconds, ring by ring

A quarter of a minute is long enough to feel like a wait and short enough that you would never set a kitchen timer for it. The dial gives up a ring every three quarters of a second, so fifteen seconds reads as a steady, fast drain rather than a flicker. Watch it once and you will not need the digits again.

In the kitchen

Fifteen seconds is a microwave number. A single tortilla softens in about that long, and a cold slice of bread goes warm without going tough. It is also the standard shake for a cocktail: shake hard until the outside of the tin frosts, which lands around fifteen seconds for most drinks with citrus or egg white. Set the dial, shake until the chime, strain.

In a workout

Fifteen seconds is a classic short rest. In the 45/15 split it is the gap between stations, just enough to move to the next exercise and shake out your arms. The interval timer page runs eight rounds of that split with a chime at each change, so you do not have to restart anything. On its own, fifteen seconds is a fair length for a short isometric hold: a hollow body, a side plank on a bad shoulder day, or a calf stretch against a wall, held to the chime and then switched.

Reading, speaking, filming

Radio spots and short video clips often run fifteen seconds, and the only way to know whether your copy fits is to read it against a clock. Start the dial as you begin and see where the chime lands. The same test works for a one-line introduction before a meeting or a single slide you have to talk over.

Longer and shorter

If fifteen feels rushed, the 20 second dial drops one ring per second, which is the easiest rhythm on the site to count along with. If you only need a quick count, 10 seconds is there. Every duration the site publishes sits on one page. Fifteen seconds also has a matching video on the card; choose Show video and the countdown plays as a clip instead of a dial.
