To determine the time difference between Eastern Standard Time and Beijing time, we must address it step by step, starting with the time zones. It is widely known that China is in the UTC+8 time zone. What about the Eastern United States? It is in the UTC-5 time zone. Once the time zones are known, the difference can be calculated using standard time difference calculation rules. The conclusion is that there is a 13-hour difference between Eastern Standard Time and Beijing time; please note that Beijing time is 13 hours ahead of Eastern Standard Time.
Additionally, when Daylight Saving Time is in effect in the Eastern United States—from the second Sunday in March to the first Sunday in November—clocks are set forward by one hour, meaning the time difference between Eastern Time and Beijing time is 12 hours.
Comparison Table of Eastern Time and Beijing Time
Next, taking September 10, 2018, as an example, this period falls during Daylight Saving Time in the United States, so a 12-hour time difference applies. The specific comparison table is provided below:
When it is 6:00 AM on September 10 in Beijing, it is 6:00 PM on September 9 in San Francisco;
When it is 7:00 AM on September 10 in Beijing, it is 7:00 PM on September 9 in San Francisco;
When it is 8:00 AM on September 10 in Beijing, it is 8:00 PM on September 9 in San Francisco;
When it is 9:00 AM on September 10 in Beijing, it is 9:00 PM on September 9 in San Francisco;
The same logic applies to the rest of this period...
When it is 8:00 PM on September 10 in Beijing, it is 8:00 AM on September 10 in San Francisco;
When it is 9:00 PM on September 10 in Beijing, it is 9:00 AM on September 10 in San Francisco;
When it is 10:00 PM on September 10 in Beijing, it is 10:00 AM on September 10 in San Francisco;
When it is 11:00 PM on September 10 in Beijing, it is 11:00 AM on September 10 in San Francisco;
When it is 12:00 AM on September 11 in Beijing, it is 12:00 PM on September 10 in San Francisco;
