How the conversion works
It moves with daylight saving: in mid-January 7 AM JST is 5 PM (EST); in mid-July it is 6 PM (EDT). The live converter above always uses today's offsets.
JST: Japan Standard Time is UTC+9 all year; South Korea shares the same offset.
EST: Eastern Time covers New York, Washington DC, Miami, Atlanta, Toronto and the east coast of the United States and Canada. It is UTC−5 in winter (EST) and UTC−4 in summer (EDT).
Full table: JST to EST converter (every hour of the day). Reverse it: EST to JST. Need an alarm at that moment? Use the zone alarm above; it rings at 6 PM EST on your device.
Questions
Will the alarm ring if I close the tab or the laptop?
No. No website can ring after the browser is closed or the computer sleeps. Keep this tab open, plug in, and the clock keeps the screen awake for you. The Ready-to-ring check under the clock shows what is set up correctly.
Does it work on my phone?
Yes on Android while the tab is open (behind other tabs is fine). On iPhone the page must stay in the foreground because Safari does not let web pages play sound from the background. Add it to the Home Screen for a full-screen bedside clock.
Is it loud enough for heavy sleepers?
Pick Loud buzzer or Siren, set the volume slider to full, and switch on the sums-to-stop option in Settings so the alarm cannot be dismissed half asleep. The sunrise light brightens the screen before the alarm too.
Can I use my own sound?
Yes. In Settings, choose an MP3, WAV or OGG file. It is stored in this browser only and never uploaded. There are also 60 built-in sounds, from a twin-bell alarm clock and a rooster to an air horn and a music box, on the sounds page.
What do the sleep sounds do?
Rain, brown noise, white noise, fan and ocean are generated in the browser and play until the alarm, then fade out as it rings. They keep the tab active through the night.
Does it need an internet connection?
Only to load the page the first time. Alarms, sounds, the sleep calculator and the sunrise math all run on your device, and the page works offline once it has been opened.
Is anything stored or sent?
Alarms and settings are saved in your browser's local storage. Nothing is sent to a server, and there is no account.
Is 7 AM JST the same as 6 PM EST every day?
Only while both zones keep the same offset. When either side enters or leaves daylight saving the answer shifts by an hour, which is why the converter recalculates from today's date.
What day is it in EST when it is 7 AM in JST?
It is the previous day in EST today; the table on the pair page shows the −1d/+1d markers for every hour.
