The Scientific Standard: The 7-Minute Workout
In the world of fitness, seven minutes is famous. It is the exact duration required to complete a full-body, science-backed exercise circuit.
High-Intensity Circuit Training (HICT)
Designed by sports scientists and popularized by the New York Times, the "7-Minute Workout" requires only your body weight, a chair, and a wall. It consists of 12 exercises (including jumping jacks, wall sits, push-ups, and planks) performed for 30 seconds each, with 10 seconds of rest in between. Pushing your body to its maximum capacity for these 420 seconds has been scientifically proven to provide many of the fitness benefits of prolonged endurance training. Set our massive 7-minute timer on your screen to track your overall survival time while you execute the circuit.
Culinary Perfection: Jammy Eggs and Herbal Teas
In the kitchen, guessing the time is a recipe for disaster. Seven minutes is the magic number for two specific delicacies.
The Perfect "Jammy" Medium-Boiled Egg
Achieving the perfect medium-boiled egg is a science. You want the egg whites to be completely firm and opaque, but the yolk must remain a thick, warm, luxurious "jam" (not liquid, but not chalky). The secret is exactly 7 minutes. Bring a pot of water to a rolling boil, gently lower your large eggs in, and instantly start our web timer. The second the 420-second alarm sounds, plunge the eggs into an ice bath.
Extracting Herbal Teas
Real tea leaves (black, green, white) will become horribly bitter if left in boiling water for seven minutes. However, herbal "tisanes" (like chamomile, peppermint, and rooibos) contain no actual tea leaves and no bitter tannins. To extract their full flavor profile and essential oils, they require a long, aggressive steep. A strict 7-minute timer ensures your herbal infusion is potent and fully developed.
Why Rely on Our Browser-Based 420-Second Timer?
The biggest flaw with most online timers is "Javascript drift." When you minimize a browser tab or switch to another window, your computer throttles the processing power to save battery. This causes simple interval timers to lose seconds and ring late.
We engineered our 7-minute timer to completely bypass this issue. Our engine locks onto your device's absolute hardware clock. Whether you are running complex background applications or letting your monitor go to sleep, our timer calculates the absolute timestamp. You get exactly 420.00 seconds of countdown, followed by a crisp, reliable audio alert. No drift, no delays, pure precision.

How long is 7 minutes in seconds?
Seven minutes is exactly 420 seconds. Our online timer tracks these 420 seconds with perfect accuracy, culminating in a clear, synthesized alarm chime.
What is the "7-Minute Scientific Workout"?
Published by the American College of Sports Medicine, the 7-Minute Workout is a science-backed circuit of 12 bodyweight exercises (like jumping jacks, wall sits, and push-ups) performed at high intensity for 30 seconds each, with 10 seconds of rest. A 7-minute timer is perfect for tracking the overarching duration of this intense block.
How long should I boil an egg to get a jammy yolk?
If you want the perfect "medium-boiled" egg—where the whites are completely firm and the yolk is a thick, jammy custard—you must boil a large egg for exactly 7 minutes. Our timer guarantees you hit this 420-second window perfectly.
Can a 7-minute timer help with ADHD?
Yes. For individuals with ADHD, starting a large task feels paralyzing. Breaking a task down into a tiny, non-threatening 7-minute sprint lowers the barrier to entry. Often, after the 7 minutes are over, hyper-focus kicks in and the individual continues working.
Will this 420-second countdown drift over time?
No. Basic JavaScript timers lose seconds when backgrounded. Our engine locks onto your device's absolute hardware clock, guaranteeing zero drift. Your 7 minutes are perfectly accurate.
Can I use this timer for brewing herbal tea?
Absolutely. Unlike green or black teas, herbal teas (like chamomile or peppermint) do not contain tannins. They require a long, 7-minute steep in boiling water to fully extract their medicinal properties and flavors.
Does this timer work on Apple Safari and iOS?
Yes, our timer is a Progressive Web App (PWA) that is fully optimized for Safari on iOS and Mac, as well as Chrome on Android and Windows.
How do I start and stop the timer?
You can toggle the 420-second countdown by clicking the massive Play/Pause button in the center of the screen, or by simply tapping the Spacebar.
Do I need to create an account to save my settings?
