How to calculate GMT to IST? ›

Indian Standard Time(IST) is 5 hours and 30 minutes ahead of Greenwich Mean Time (GMT). If anytime you would like to know the current time IN IST just add 5 hours and 30 minutes to GMT time.

Indian Standard Time (IST) is the time zone observed throughout India. It does not take into account daylight saving time along with other seasonal factors. India has only one time zone. *IST is ahead of GMT by 5:30 Hours.

IST is 5:30 hours ahead of GMT. Since, IST is 5:30 hours ahead of GMT, then if Indian Standard Time (IST) is at 7 am, then Greenwich will be at 12:30 pm. Note: The prime meridian is a hypothetical reference life that is used to create charts and maps. It can also be used to calculate a country's time.

Just add(or subtract) the time needed: =A1 + Time(8,0,0) where 8 would be the number of hours to add. So in this case, =A1+Time(5,30,0) , or =A1+5.5/24 .

C2 formula: This formula assumes that the local time is in IST (Indian Standard Time) and subtracts 5 hours and 30 minutes to convert it to GMT.

Greenwich Mean Time is calculated by using the sun. When the sun is at its highest point, exactly above the Prime Meridian, this means that it is 12:00 noon at Greenwich.

Legally, the civil time used in the UK is called "Greenwich mean time" (without capitalisation), with an exception made for those periods when the Summer Time Act 1972 orders an hour's shift for daylight saving.

Greenwich Mean Time is the yearly average (or 'mean') of the time each day when the Sun crosses the Prime Meridian at the Royal Observatory Greenwich. Essentially, mean time is clock time rather than solar (astronomical) time.

var s = new Date('2020-01-14T17:43:37.000Z'). toLocaleString(undefined, {timeZone: 'Asia/Kolkata'}); This will do the correct time zone conversion, as the input is in UTC (as specified by the Z at the end). undefined means to use the user's locale for the formatting of the date and time.
