18 minutes
An online timer for 18 minutes displays the remaining time and keeps an accurate countdown without delay. The built-in time calculator automatically calculates the duration of 18 minutes in seconds. The controls-start, pause, and reset — are intuitive and accessible with just one click. Full-screen mode is also available: it is convenient to use the timer during demonstrations, presentations, or sports activities. At the end of the timer, a beep sounds — you can select the desired melody or completely mute the sound.
The interface adapts to any screen size and works stably on phones, tablets, and computers. Switching between tabs does not affect the accuracy of operation: the current timer status is saved and displayed in the browser tab header.
An online 18 minutes timer is often used for work intervals, sports sets, cooking, household chores, and Pomodoro-style sessions. The countdown helps you stay focused and stick to the chosen interval.
