Mexico City is 11 hours behind Karachi for most of the year: when it is 10:00 am in Karachi it is 11:00 pm (previous day) in Mexico City. In offset terms Karachi is on UTC+05:00 and Mexico City is on UTC-06:00 in January, and UTC+05:00 and UTC-06:00 in July. The converter above works from your browser’s own time zone data, so the figure it shows is the one in force today rather than the one that was in force when this page was written.
Neither city changes its clocks. Karachi stays on UTC+05:00 and Mexico City stays on UTC-06:00 all year. The difference is therefore fixed for all of 2026, which makes this one of the few city pairs where a single number is the whole answer: Mexico City is always 11 hours behind Karachi. Recurring meetings between the two never drift, and the table below confirms it period by period.
There is no overlap in office hours at all. Karachi works 09:00 to 17:00 and Mexico City works 09:00 to 18:00, and with 11 hours between them one city has closed before the other opens. Anything live has to be early for one side or late for the other; 17:00 to 18:00 in Karachi, which is 06:00 to 07:00 in Mexico City, is usually the least painful compromise. Both cities work Monday to Friday, so only the clock has to be reconciled.
Two local details worth knowing. Pakistan keeps UTC+05:00 all year, half an hour behind India, which is the usual source of confusion on regional calls. Mexico abolished nationwide daylight saving in 2022, so the gap to the United States now changes when the US switches rather than when Mexico does.
Write the invitation in both clocks. "10:00 Karachi / 23:00 Mexico City" removes the ambiguity that abbreviations introduce — Karachi alone is read as PKT in winter and PKT in summer, and calendar software will happily convert one into the other without telling you.
The formula
local Karachi- The time you enter, on the Karachi clock
offset- Each city’s UTC offset at that moment, read live from the IANA time zone database in your browser
−11- The difference in hours that holds for most of 2026: Mexico City is 11 hours behind Karachi
day shift- Whether the converted time falls on the previous, same or next calendar day in Mexico City
How it works, step by step
- Enter a time in Karachi using the 24-hour hour box and the minute box — 15:30 is hour 15, minute 30.
- Your browser reports the UTC offset in force in Karachi and in Mexico City for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 11 hour rule.
- The second offset minus the first gives the difference, which is added to the time you entered. A result past midnight is marked as the next or previous day, because that is where most conversion mistakes live.
- The panel also shows the current time in both cities, the date in Mexico City, and whether the two offices are open at the same moment.
Worked examples
09:00 in Karachi
09:00 in Karachi is 22:00 in Mexico City (previous day) — late at night in Mexico City. In 12-hour terms, 9:00 am against 10:00 pm (previous day). Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
12:00 in Karachi
12:00 in Karachi is 01:00 in Mexico City — the middle of the night in Mexico City. In 12-hour terms, 12:00 pm against 1:00 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
16:00 in Karachi
16:00 in Karachi is 05:00 in Mexico City — the middle of the night in Mexico City. In 12-hour terms, 4:00 pm against 5:00 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
23:00 in Karachi, and the date problem
23:00 in Karachi is 12:00 in Mexico City on the same day. This is where conversions go wrong in writing: the time is right, the day is not, and a meeting invitation sent for "Tuesday" arrives for the wrong Tuesday. Give the date in both cities whenever the converted time is near midnight.
How to read your score
Frequently asked questions
How many hours behind Karachi is Mexico City?
Mexico City is 11 hours behind Karachi for most of 2026, so 09:00 in Karachi is 22:00 in Mexico City (previous day). That difference holds for the whole year, because the two clocks either never change or change on the same dates — the table on this page confirms it period by period.
What is 2 pm Karachi time in Mexico City?
3:00 am, the middle of the night in Mexico City. In 24-hour form 14:00 in Karachi is 03:00 in Mexico City, and that is outside working hours in Mexico City.
What is the best time to call between Karachi and Mexico City?
There is no time when both offices are open, so one side has to step outside its normal hours. The two least disruptive options are 08:00 in Karachi, which is 21:00 in Mexico City, or 17:00 in Karachi, which is 06:00 in Mexico City.
Is Mexico City ahead of or behind Karachi?
Mexico City is behind. Karachi is at UTC+05:00 and Mexico City is at UTC-06:00 in mid-January, and UTC+05:00 and UTC-06:00 in mid-July. The clock moves back going from Karachi to Mexico City, which is why Karachi reaches the end of its working day first.
Do Karachi and Mexico City change their clocks on the same date?
Neither city changes its clocks. In 2026, Karachi does not change its clocks at all, and Mexico City does not change its clocks at all. The difference between the two cities therefore holds all year.
What do the abbreviations for Karachi mean?
Karachi is on PKT in winter and PKT in summer, while Mexico City uses CST and CST. Abbreviations are the least reliable way to write a time: several are ambiguous between regions, and the summer and winter forms are an hour apart. A UTC offset, or the time given in both cities, cannot be misread.
Does this converter stay correct after the clocks change?
Yes. It does not use a stored number for the difference. Each time you change a value it asks your browser for the UTC offset that Asia/Karachi and America/Mexico_City are on at that moment, using the IANA time zone database that ships with your operating system, and takes the difference. The tables on this page are computed from the same database for 2026.
