Pakistan has experimented with Daylight Saving Time (DST) a number of times since 2002, shifting local time from UTC+05:00 to UTC+06:00 during various summer periods. Daylight saving time in Pakistan has not been observed since 2009. Daylight Saving Time starts on 9 February 2025 and ends on 7 September 2025.
This is a list representing time zones by country. Countries are ranked by total number of time zones on their territory. Time zones of a country include that of dependent territories (except Antarctic claims). France, including its overseas territories, has the most time zones with 12 (13 including its claim in Antarctica and all other counties).
On 15 September 1951, following the findings of mathematician Mahmood Anwar, two time zones were introduced. Karachi Time (KART) was introduced in West Pakistan by subtracting 30 minutes from UTC+05:30 to UTC+05:00, while Dacca Time (DACT) was introduced in East Pakistan by subtracting 30 minutes off UTC+06:30 to UTC+06:00.
The time differences may also result in different dates. For example, when it is 22:00 on Monday in Egypt (UTC+02:00), it is 01:00 on Tuesday in Pakistan (UTC+05:00). The table "Time of day by zone" gives an overview on the time relations between different zones.
Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+08:00), Cuba Standard Time (UTC−05:00), and (North American) Central Standard Time (UTC−06:00), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in ...
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, and the state of Quintana Roo in Mexico. Eastern Standard Time (EST) is five hours behind Coordinated Universal Time (UTC−05:00).
TT differs from Geocentric Coordinate Time (TCG) by a constant rate. Formally it is defined by the equation = +, where TT and TCG are linear counts of SI seconds in Terrestrial Time and Geocentric Coordinate Time respectively, is the constant difference in the rates of the two time scales, and is a constant to resolve the epochs (see below).
Since 2002, Pakistan has implemented Daylight Saving Time (DST) multiple times, adjusting local time from UTC+05:00 to UTC+06:00 during different summer periods. In 2002, DST was observed from the first Sunday in April (April 7) at 00:00 to the first Sunday in October (October 6) at 00:00.
