Time ZonesAbout this time zone
Merida is one of the 12 time zone areas of Mexico. Computers and phones know it by the zone name America/Merida. Its time is UTC−6, which means it is 6 hours behind Coordinated Universal Time (UTC) all year round. The short name used for this time is CST. Compared with India (IST), it is 11 hours 30 minutes behind India.
Clock changes in 2026 and 2027
Merida does not change its clocks in 2026 or 2027. The time stays at UTC−6 all year, so there is no daylight saving time to remember.

Clock time and sun time in Merida
A time zone is an agreement, and the sun does not follow it exactly. Mérida, the largest city in this zone, lies at about 89.6° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 5 hours 58 minutes behind UTC. The clock is set to UTC−6. The sun is therefore highest in the sky at about 11:58 am by the clock, not at 12:00. That is a close match: clock and sun agree to within a quarter of an hour. Other places in the zone, to the east or west of Mérida, see the sun peak a little earlier or later. Through the year the figure also drifts by up to a quarter of an hour either way.
How long the day is
Mérida is about 21° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 13 hours 24 minutes. On the shortest, around 21 December, for about 10 hours 51 minutes. The difference between summer and winter is about 2 hours 33 minutes, and the clocks stay the same all year.
Office hours shared with other places
If both sides work from 9 am to 6 pm, these are the hours when a call falls inside the working day at both ends. Times are for Merida.
- With India, all year: no shared office hour: 9:00 am here is 8:30 pm in India, and 6:00 pm here is 5:30 am there, so one side has to start early or stay late.
- With London, in January: 9:00 am to 12:00 pm here, which is 3:00 pm to 6:00 pm in London (3 hours shared). In July: 9:00 am to 11:00 am here, which is 4:00 pm to 6:00 pm in London (2 hours shared).
- With New York, in January: 9:00 am to 5:00 pm here, which is 10:00 am to 6:00 pm in New York (8 hours shared). In July: 9:00 am to 4:00 pm here, which is 11:00 am to 6:00 pm in New York (7 hours shared).
