What are IST, EST, CST, MST and PST?

Time zone abbreviations are commonly used to describe different regions. IST is commonly used for India Standard Time. In the United States, Eastern, Central, Mountain and Pacific Time are often abbreviated as ET, CT, MT and PT.

Standard-time abbreviations such as EST, CST, MST and PST can be confusing because many locations change their clocks for daylight saving time. For this reason, a geographic time-zone identifier such as America/New_Yorkor America/Chicagois more reliable for software calculations.

Time zones and daylight saving time

Some countries and regions change their clocks during part of the year. This means that the difference between two locations may change depending on the date.

For example, the difference between India and a US location can change when the US changes between standard time and daylight time. Always include the date when converting between locations that observe daylight saving time.

Why use a time zone converter?

International schedules can become difficult when people live in different time zones. A time zone converter makes it easier to check the local time before arranging a meeting, phone call, interview, webinar or other event.

The converter can also help compare popular locations such as New York, Chicago, Denver, Los Angeles, London, Paris, Berlin, Mumbai, Tokyo and Sydney.

FAQ on Time Zone

1. What is a time zone converter?

A time zone converter changes a date and time from one geographic time zone to another.

2. How do I convert IST to US time?

Select India Standard Time as the starting time zone and choose the required US location, such as New York, Chicago, Denver or Los Angeles. Then select the date and time to see the corresponding local time.

3. Is CST always one hour ahead of MST?

The answer depends on the geographic locations and the date. Daylight saving time can change the offset used by a location, so a date-aware converter is more reliable than a fixed abbreviation-to-offset calculation.

4. Does this converter account for daylight saving time?

Yes. The converter uses geographic time-zone identifiers provided by the browser's internationalization system, allowing the selected date to be considered when determining the local time.

5. Can I convert UTC to IST?

Yes. Select UTC as the source time zone and India Standard Time as the destination.
