20 Minute Timer
Twenty-minute countdown — conference-talk territory. Pre-configured and fullscreen-ready.
A 20 minute timer is the canonical "conference talk" length. The standard TEDx slot is 18-20 minutes; most user-group meetups give speakers 20 minutes for a polished presentation; the Pomodoro variant called "Animedoro" uses 20-minute work blocks. Outside of presenting, 20 minutes is a productive deep-work interval that's long enough to engage with a real problem but short enough that the visible countdown maintains urgency.
This tool gives you a clean fullscreen 20-minute countdown that's ready to start in two clicks. Pre-configured to 20:00, no signup, no ads, no notifications. Hit Start to launch the timer; hit Fullscreen to make the countdown fill the screen (perfect for stage projection or a second monitor visible to the speaker but not the audience). The color themes are tuned for different room conditions — white-on-black for dim stages, black-on-white for projectors, yellow-on-black for accessibility — and you can pick mono digital or humanist for the digit style.
The setup pairs especially well with our teleprompter tool — many speakers run the teleprompter on one monitor and this timer on a second, watching the countdown from peripheral vision while reading the speech. Add interim alerts at 5:00 (one-quarter to go), 2:00 (almost done), and 0:30 (wrap-up) so you don't need to actively monitor the screen mid-flow — the timer beeps and pulses at each checkpoint.
Common 20-minute uses: TEDx and conference talks with the 18-20 minute format; Pomodoro variants like Animedoro (20 minutes focus + 5 break); fitness intervals for tabata-style structured workouts; client-meeting time-boxing for tight project-review blocks; kids' practice timers for piano or sports drills.

Frequently asked questions
Is 20 minutes the right length for a conference talk?
It's one of the canonical lengths — TEDx talks are 18-20 minutes, many user-group meetups give speakers 20 minutes, and most product-pitch slots at investor demo days are 5-20 minutes. The 20-minute length forces tight editing — you have to drop tangents and keep momentum — but isn't so short that you can only fit a single idea. If you're given 20 minutes for a talk, plan for 18 minutes of content and leave 2 minutes for inevitable transition delays and audience laughter.
Can I use this timer on a second monitor while presenting?
Yes — open the timer page in a new browser window, drag it to your secondary monitor (or extend a laptop display), hit Fullscreen on that window. Your primary display shows your slides; the secondary shows just the countdown. You can monitor it from peripheral vision without breaking eye contact with the audience.
What's the difference between a 20 minute timer and a 25 minute Pomodoro?
A 20-minute timer is a single-block countdown — you start, it counts down, it stops. A Pomodoro is a structured technique with 25-minute focused-work blocks separated by 5-minute breaks. The 20-minute variant (sometimes called Animedoro) is a less-formal alternative for people who find the 25-minute Pomodoro slightly too long; the discipline is the same but the timeboxes are shorter. Use whichever rhythm fits your attention span.
Can I see the timer count down without dedicating my screen to it?
Yes — minimize the timer window or place it in a corner of your screen. The page title updates with the remaining time (so you can see it in the browser tab or the OS taskbar even when the window isn't visible). For passive monitoring while working in another app, this is the lowest-friction approach.
Will the timer save my settings (color, font, alerts) between sessions?
Yes — preferences auto-save to your browser's local storage. When you visit the page again, your last theme, font, and alert configuration are restored. You can clear them by clearing browser local storage if you want to start fresh.
