★ TIME CONVERTER · TIME & DATE · BEIJING
China Standard Time is UTC+8 year-round: China observes NO daylight saving time, ever. At 12:00 CST on October 24, 2026, it is 04:00 UTC the same day, 00:00 EDT on October 24 in the east, but already the previous evening in the west: 23:00 CDT on October 23, 22:00 MDT on October 23, and 21:00 PDT on October 23. Enter any Beijing date and time below: the converter subtracts 8 hours to reach UTC, then reads every US zone from that same moment.
The trap with Beijing is the date, not the offset. Beijing is 12 hours ahead of Eastern in the daylight period and 13 hours ahead in standard time, so a Beijing midday is midnight in the east and the previous evening everywhere else in the US. Enter the Beijing date, not just the time, and the converter uses the US daylight saving rules in force on that date.
CST is UTC+8 year-round: China does not observe daylight saving time, so there is no CST/CDT pair and no spring-forward or fall-back date to remember. UTC = Beijing time − 8 hours. US times are then read from that UTC moment using the US zone rules in force on the entered date: Eastern is UTC−4 in daylight time and UTC−5 in standard time, Central UTC−5 / UTC−6, Mountain UTC−6 / UTC−7, Pacific UTC−7 / UTC−8. This converter works from the fixed Beijing offset, never from a Beijing daylight saving conversion, because there is none. Note that all of China runs on this single time, from Beijing to Urumqi, even though the sun sets hours later in the west.
Setup: 12:00 CST on October 24, 2026, when the US is on daylight time.
Line 1 — UTC. 12:00 − 8 hours = 04:00 UTC on October 24.
Line 2 — Eastern. 04:00 UTC − 4 hours (EDT) = 00:00 EDT on October 24 — midnight, exactly.
Line 3 — Central. 04:00 UTC − 5 hours (CDT) = 23:00 CDT on October 23 — the previous evening.
Line 4 — Mountain. 04:00 UTC − 6 hours (MDT) = 22:00 MDT on October 23.
Line 5 — Pacific. 04:00 UTC − 7 hours (PDT) = 21:00 PDT on October 23.
Winter: 12:00 CST on January 15, 2026. UTC is still 04:00, but the US has fallen back: 23:00 EST Eastern on January 14, 22:00 CST Central on January 14, 21:00 MST Mountain on January 14, and 20:00 PST Pacific on January 14. Every US time is one hour earlier than in October, and now even the east is on the previous day.
The gap widens in winter. In the daylight period Beijing sits 12 hours ahead of Eastern, 11 ahead of Central, 10 ahead of Mountain, and 9 ahead of Pacific. In standard time those gaps are 13, 12, 11, and 10 hours. The gap widens by 1 hour in winter because US clocks fall back while Beijing stays put.
Why the date matters more than the time. Noon Beijing time is midnight Eastern in October and 11 p.m. Eastern the previous day in January, and it crosses the US date line between Eastern and Central in October, and before Eastern in January. A recurring meeting set by Beijing time shifts on the US calendar twice a year, at the US daylight saving changes, even though nothing in Beijing changes at all.
The date-change trap, stated plainly. Beijing is a day ahead of US evenings: Beijing daytime is US nighttime, and Beijing evening is the small hours of the US morning. If you book a "Friday" call from Beijing without checking, your US counterpart may be joining on Thursday night — or, in winter, even your Eastern counterpart is on Thursday. Always read the US date the converter prints, not just the US clock time.
| Output | Formula | What it means |
|---|---|---|
| UTC | Beijing time − 8 hours | 04:00 UTC at the defaults — the same moment on the world clock, every day of the year. |
| Eastern | UTC − 4 hours (EDT) / − 5 hours (EST) | 00:00 EDT on October 24 at the defaults; 23:00 EST on January 14 in winter. |
| Central | UTC − 5 hours (CDT) / − 6 hours (CST) | 23:00 CDT on October 23 at the defaults; 22:00 CST on January 14 in winter. |
| Mountain | UTC − 6 hours (MDT) / − 7 hours (MST) | 22:00 MDT on October 23 at the defaults; 21:00 MST on January 14 in winter. |
| Pacific | UTC − 7 hours (PDT) / − 8 hours (PST) | 21:00 PDT on October 23 at the defaults; 20:00 PST on January 14 in winter. |
The conversion is exact for the entered date and time, because the Beijing offset never changes. The only subtlety is the US daylight saving transitions themselves: on the two US changeover Sundays, a US clock time near 2:00 a.m. may be ambiguous or skipped, and the converter reads the US zone from the UTC moment, which is the unambiguous way to resolve it. This is a converter, not a live clock: it converts the time you enter and does not track the current time. Do not confuse CST here (China Standard Time, UTC+8) with US Central Standard Time, which also abbreviates to CST but is UTC−6 — the page always says which CST it means. Error policy: malformed or out-of-range dates and times, and calendar dates that do not exist, are reported as errors rather than converted.
Bright Side Kit. "Beijing Time Converter: CST to US Time." https://brightoolbox.com/beijing-time-converter/ Accessed October 24, 2026.No. China stays on CST, UTC+8, all year. China last observed daylight saving in 1991 and has not shifted since. That fixed offset is why the converter subtracts exactly 8 hours to reach UTC on every date.
00:00 CST the next day in the daylight period, 01:00 CST the next day in standard time. Beijing is 12 hours ahead of Eastern in summer and 13 hours ahead in winter, because only the US moves.
Because the US falls back and Beijing does not. 12:00 CST is 00:00 EDT in October but 23:00 EST the previous day in January. The gap widens by 1 hour in winter on every US zone.
Yes, officially. All of China uses CST, UTC+8, even though the country spans five geographic time zones. Solar noon in western China falls hours after clock noon, which is why the single time zone surprises visitors.
UTC+8, always. Subtract 8 hours from any Beijing time to get UTC: 12:00 CST is 04:00 UTC on every day of the year, summer and winter alike.
No, it converts the time you enter. Enter the Beijing date and time you care about — a meeting, a flight, a call — and it shows every zone at that same moment.
Yes, routinely. Beijing is far ahead of the US, so Beijing daytime is US nighttime of the previous day in Central, Mountain, and Pacific time in October, and in all four US zones in winter. Always check the US date for Beijing daytime calls, not just the clock.
Because US daylight saving rules depend on the date. Without the date the converter could not know whether the US is on daylight or standard time, and the answer would be off by an hour for half the year — and on the wrong day near midnight.
