Measuring… (about 15 seconds)

When should I click?

If you wait to see the digits change, your reaction adds about 0.2 s. Turn on the 3-2-1 beeps and click on the rhythm, so your finger lands with the last high beep.

Clicking too early can get you rejected as “not open yet”. Don’t click before the time above. The time above already allows for how long your click takes to reach the server (measured, at most 0.03 s). It can’t include the queue at the moment of opening, which nobody can measure in advance.

When exactly should you click for a ticket sale, drop or class registration?

Time zones only change how times are displayed. How far a server’s clock is off is the same wherever you are. We don’t use your location; we only read your browser’s time zone setting on this device.

Measurement history

Server clocks drift slowly. Right before an opening, servers get busy and measurements get less precise, so we use the most precise reading from the last 15 minutes.

My device

How it works: servers stamp each response with the time (to the second). We request it right as the server’s second ticks over, many times, to narrow it down to milliseconds. Standard time comes from the Korea Research Institute of Standards and Science (KRISS) NTP. This measures the web server’s clock, which can differ from internal booking servers.

How to read this page

The big clock is this site’s server clock, corrected for your device. The colored card tells you whether the server is ahead of, behind, or in step with standard time, and by how much.

How to use

Set the opening date and time (in the site’s local time).
Keep the countdown beeps on. You’ll hear 3·2·1 and a higher tone at the exact moment, even if this tab is in the background.
Click the moment the big clock shows the opening time. If you watch another clock, use the times under “When should I click?”.
Use Add to calendar to get a reminder 5 minutes before, or Copy link to share this exact countdown.

Tips

Don’t click early: many sites reject requests that arrive before opening.
Open this page a few minutes before. Right at opening, servers get slow and measurements less precise, so we keep the best reading from the last 15 minutes.
Some sites run several servers with different clocks. On one ticket site they disagreed by up to 0.7 s. When servers disagree, we use the slowest one.
