Why KST is the K-pop reference clock
Korean Standard Time (KST, UTC+9) is the canonical reference clock for the K-pop industry. Every comeback, music video, music show appearance, on-sale announcement, and tour reveal is timestamped in KST first; international fans translate that time into their own clocks afterward. South Korea does not observe daylight saving time, so KST is always exactly UTC+9 — the same offset as Tokyo, eight hours ahead of London (in winter) or seven (in summer), thirteen hours ahead of New York (in winter), and sixteen hours ahead of Los Angeles (in winter).
Common KST release windows
18:00 KST (6:00 PM Seoul)
The single most common comeback release time. Music videos and lead singles drop at 18:00 KST on a weekday — usually Monday for boy groups, sometimes Tuesday or Friday. This translates to 1:00 AM Pacific Time on the same day in North America (the night before for some fans), 4:00 AM Eastern Time, and 9:00 AM London time. Set your alarm.
00:00 KST (Midnight Seoul)
Album track-list releases, teaser videos, and digital album drops often go live at midnight KST. This is 8:00 AM Pacific Time the day before, 11:00 AM Eastern, and 4:00 PM London. Convenient if you're in the Americas.
20:00 KST (8:00 PM Seoul)
Some music shows, V-LIVE/Weverse Live broadcasts, and special program drops fall here. This corresponds to 3:00 AM Pacific (the next day in Korea, but still the previous day in California), 6:00 AM Eastern, and 11:00 AM London.
Daylight Saving Time gotchas
South Korea, Japan, and Singapore do not observe daylight saving time. The United States and the United Kingdom do. This means the difference between KST and Los Angeles, KST and New York, or KST and London changes by one hour twice a year (usually in March and November/October). Our converter handles this automatically based on the date you input — but if you're doing mental math, remember that summertime in the US/UK shifts the offset by an hour.
How to plan an early-morning comeback
If you're in North America, the most common K-pop comeback time (18:00 KST on a weekday) lands at 1:00 AM PT or 4:00 AM ET. Many fans stream the music video live as it drops to support the artist on the charts; others queue the video and watch it at a more reasonable hour. A few practical tips for catching a live drop: set two alarms (one at the drop minute, another 5 minutes earlier), pre-load the YouTube channel page with notifications enabled, ensure your audio is off if you're in a shared sleep space, and consider a brief nap beforehand if the drop falls in the middle of your night.
Using the converter for live broadcasts
Beyond comebacks, this converter is useful for: M Countdown / Music Bank / Show Champion / Inkigayo / The Show appearance times, KCON and MAMA awards broadcasts, Weverse Live and V-Live (now consolidated into Weverse) sessions, tour ticket on-sale times (these often differ between Korean, Japanese, US, and EU markets — check the Yes24/Interpark/Ticketmaster page for your regional on-sale window), and global voting deadlines for music shows and year-end awards. When in doubt, screenshot your converted time and double-check against the official announcement.
Why we picked these six cities
Our six default cities (Seoul, Tokyo, Los Angeles, New York, London, Singapore) cover the largest international K-pop fan markets by audience size. Tokyo and Seoul are the two most active touring markets. Los Angeles, New York, and London are the largest English-speaking K-pop hubs. Singapore is the gateway for Southeast Asian K-pop fandom. If you need additional cities (Mexico City, São Paulo, Sydney, Mumbai, Toronto, Manila, Dubai), email us — we're considering adding a custom city picker in Phase 2.
Frequently asked questions
Is KST the same as JST?
Yes. Korean Standard Time and Japan Standard Time are both UTC+9 and have been since 1961. A 6:00 PM KST drop is the same wall-clock moment as 6:00 PM JST.
What about North Korea's "Pyongyang Time"?
Not relevant for K-pop. Although North Korea briefly used UTC+8:30 ("Pyongyang Time") between 2015 and 2018, it has since reverted to UTC+9 to align with South Korea. K-pop is a South Korean industry and uses KST throughout.
Why does the website show times in my own timezone too?
Across K-Event Calendar, every event time is displayed in two formats: the event's local timezone (where the concert/comeback is happening) and your device's timezone (translated automatically on page load). This converter is for cases where you specifically need a KST → other-city mapping, like when you're reading a Korean tweet that says "6시 드랍" (6 PM drop) and need to know when that lands in your city.
