What is 10:00 am GMT in IST?

Solution

10:00 am GMT is

3:00 pm IST

Here, we have calculated the local time in India Standard Time based on the given time of 10:00 am in Greenwich Mean Time. Our precise algorithm takes into account various factors, such as daylight saving time and the specific offset between the two time zones, to provide you with an accurate conversion.

Did you know?

Before the establishment of standardized time zones, local times were determined by each city's own solar noon (the time when the Sun is at its highest point in the sky).

How to calculate 10:00 am GMT to IST yourself:

  1. Identify the time zones: Determine the time zones for both the starting location (GMT) and the destination location (IST).
  2. Calculate the offset: Find the difference in hours (and sometimes minutes) between the two time zones. This is usually expressed as a positive or negative offset from Coordinated Universal Time (UTC). In this case, the offset between Greenwich Mean Time and India Standard Time is 5 hours.
  3. Consider daylight saving time: Check if either the starting or destination time zone is currently observing daylight saving time. If so, make sure to adjust your calculation by adding or subtracting one hour as needed.
  4. Apply the offset: Add or subtract the calculated offset to the given time in the starting time zone (10:00 am). Be mindful of any potential "wrap-around" when crossing the International Date Line or switching between AM and PM.

By following these steps, you can convert the time between Greenwich Mean Time and India Standard Time accurately. However, if you prefer a hassle-free way to find the time in another part of the world, feel free to use our Time Zone Conversion Calculator on the directory page.

Greenwich Mean Time

Greenwich Mean Time (GMT) is the time zone used as the basis for calculating time differences worldwide. It is the same as Coordinated Universal Time (UTC) and has no associated cities, as it serves as a reference point for all other time zones.

India Standard Time

India Standard Time (IST) is the time zone observed throughout India, including cities like New Delhi and Mumbai. It is 5 hours and 30 minutes ahead of UTC and does not observe daylight saving time.

Cities:

  • New Delhi
  • Mumbai
  • Kolkata
  • Bangalore
  • Chennai
