8 Minute Timer
Eight minutes is 480 seconds. It does not divide an hour, since seven runs land at 56 minutes, but fifteen runs come to exactly two hours, and sunlight takes a little over eight to reach us.

Nothing plays until you press start.
480 seconds
Eight is one of the awkward lengths. Seven runs make 56 minutes and it takes seven and a half to fill an hour, so eight never became a scheduling unit the way ten and fifteen did. Stack it higher and it comes good: fifteen back-to-back eight-minute runs are exactly 120 minutes, two hours on the nose.
The eight-minute distance to the Sun
Light takes about eight minutes and twenty seconds, roughly 500 seconds, to travel from the Sun to Earth. Start this timer at the moment a photon leaves and it hits zero about twenty seconds before the light arrives. It is the usual way of answering how far away the Sun is in time rather than in kilometres, and eight minutes is the closest round number to it.
What eight minutes gets used for
- Dried pasta. Packets commonly ask for eight to ten minutes for al dente, with the shorter end for thin shapes.
- Timed rounds at speed-dating and structured networking events, which are often set somewhere between four and eight minutes.
- A single focused block for people who find ten minutes long enough to negotiate with.
- One leg of a longer session, run seven or fifteen times depending on whether you are aiming at an hour or two.
Before you rely on it
The countdown reads the system clock, so leaving the tab does not slow it and the number is still correct when you return. The tone at zero is the part that can fail, particularly on a phone that has gone to sleep. Do not rely on it for medication, an exam or a cooking step that burns. Other lengths are on the timer page.
