This EST to CST converter turns any time in Eastern Standard Time (EST) into China Standard Time (CST), using your device clock so daylight saving is applied automatically. CST is 13 hours ahead of EST when both zones are on standard time, and 12 hours ahead during the summer months when clocks have shifted. EST is UTC−5 (EDT: UTC−4); CST is UTC+8.
EST covers New York, Toronto, Miami; CST covers Beijing, Shanghai, Shenzhen. Because only EST observes daylight saving time, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between EST and CST?
CST is 13 hours ahead of EST on standard time. During daylight saving the gap changes to 12 hours. That comes from the UTC offsets: EST is UTC−5 and CST is UTC+8. For example, 9 am EST = 10 pm CST, and in summer 9 am EST = 9 pm CST.
Is CST ahead of or behind EST?
CST is 13 hours ahead of EST, so when it is noon in EST it is 1 am in CST the next day. Ahead means the clock there already shows a later time; a call at 5 pm EST lands at 6 am CST.
Does EST or CST observe daylight saving time in 2026?
EST switches to EDT (UTC−4) on March 8 and back on November 1 in 2026. CST keeps UTC+8 all year. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between EST and CST?
Office hours (9 am to 5 pm) do not overlap at all with a 13 hours difference. The least painful options are early morning in EST or early evening in CST; for example 8 am EST = 9 pm CST and 6 pm EST = 7 am CST the next day. Rotate the inconvenient slot between the two sides for recurring calls.
Which cities use EST and CST?
EST (Eastern Standard Time) is used in New York, Toronto, Miami, Atlanta. CST (China Standard Time) is used in Beijing, Shanghai, Shenzhen, Taipei. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
