Time in Pakistan refers to the standard time observed throughout the Islamic Republic of Pakistan. The country uses a single time zone:
- Pakistan Standard Time (PKT) – UTC+05:00.
PKT is five hours ahead of Coordinated Universal Time (UTC+05:00) and does not observe daylight saving time (DST) under the current legal framework.
Legal and Administrative Basis
The time zone is defined by the Government of Pakistan under the Pakistan Standard Time Act, 1969, which states that the whole territory shall observe a uniform time of five hours ahead of Greenwich Mean Time (GMT+5). The legislation has been amended periodically, but the offset has remained unchanged since its establishment.
IANA Time Zone Database
In the Internet Assigned Numbers Authority (IANA) tz database, which is widely used for computing and software applications, the time zone for Pakistan is listed as Asia/Karachi. This entry reflects the UTC+05:00 offset and includes historical records of any temporary DST observances.
Historical Use of Daylight Saving Time
Pakistan has experimented with daylight saving time on three separate occasions:
| Year | Period of DST | Offset during DST |
|---|---|---|
| 2002 | 1 April – 31 October | UTC+06:00 |
| 2008 | 1 June – 31 October | UTC+06:00 |
| 2009 | 15 May – 31 October | UTC+06:00 |
These measures were introduced to alleviate energy shortages but were discontinued after each trial period. Since 2010, Pakistan has not reinstated DST, and PKT remains the sole legal time throughout the year.
Relation to Neighboring Countries
PKT aligns with the standard time used by neighboring Kazakhstan (West Kazakhstan Time) and Turkmenistan, both also at UTC+05:00. However, it differs from India (UTC+05:30) and Afghanistan (UTC+04:30).
Practical Implications
All civil, commercial, and governmental activities in Pakistan—such as business hours, transportation schedules, broadcasting, and public services—are coordinated according to PKT. Internationally, the time zone is often referenced in diplomatic communications and in global financial markets where Pakistan participates.
