Best time to call Bogotá from Beijing
For most work calls, compare the normal business day in Beijing (BJT) with the business day in Bogotá (COT). BJT commonly covers East Asia, while COT is mainly associated with South America.
⚠️ Note: 2026-07-05 is not a normal workday in one or both regions based on their configured calendar. The overlap below should be treated as a reference, not a guaranteed office-hours window.
⚠️ There is no clean same-day business-hours overlap on 2026-07-05. A practical compromise is around 10:00 PM BJT, which reaches 9:00 AM COT near the start of their workday.
- DST Safety: Neither BJT nor COT uses Daylight Saving Time in our dataset, making business-hour relationships stable year-round.
- Shanghai Stock Exchange (SSE): 09:30-15:00 local time in Shanghai.
- Colombia Stock Exchange (BVC): 09:30-16:00 local time in Bogotá.

Frequently Asked Questions
What is the time difference between BJT and COT?
During standard time, Colombia Time is 13 hours behind Beijing Time.
Does China observe Daylight Saving Time?
Mainland China abolished Daylight Saving Time in 1991 and has remained permanently fixed at UTC+8:00 ever since, with no seasonal clock adjustment at any point in the year. This means the offset between Beijing or Shanghai and any DST-observing country shifts by one hour twice annually when those countries change their clocks — but BJT itself never moves.
How many time zones are there in China?
Despite spanning a geographical width that would naturally encompass five separate time zones — from the eastern coast at roughly UTC+8 to the western reaches of Xinjiang near UTC+6 or even UTC+5 — China officially mandates a single unified time zone, Beijing Time (BJT) at UTC+8:00, across the entire country. This policy has been in place since 1949 and applies to all 34 provincial-level administrative regions without exception.
Does Colombia observe Daylight Saving Time?
Colombia does not observe Daylight Saving Time and has no current plans to do so. COT remains fixed at UTC-05:00 every day of the year, providing a consistent, unchanging reference point for international business and logistics.
How does Colombia Time (COT) align with the US?
COT (UTC-05:00) matches US Eastern Standard Time (EST) exactly during the Northern Hemisphere winter, creating zero offset between Bogotá and New York. During US Daylight Saving Time in summer, COT runs one hour behind Eastern Daylight Time (EDT, UTC-04:00), maintaining a gap narrow enough that a full shared workday remains easily achievable — one of the tightest nearshore alignments available from South America.
