In the following chart, Eastern Standard Time (EST) is compared with Indian Standard Time (IST).
This chart is fine as long as Daylight Saving Time (DST) is not observed. DST or summer time is the practice of advancing clocks during the summer months that have more daylight, so that people get up earlier in the morning and experience more daylight in the evening. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in the autumn.
Many cities in USA calculate time as per DST. For example, when it is 8:30 p.m. (IST) in New Delhi, India, it is 11:00 a.m. (DST) in New York, USA. If you go by the above chart then it is 10:00 a.m. (EST) in New York. So, if your chosen city observes DST, then the above chart is about one hour late. However, remembering which cities observe DST is not practical and thus, help from online resources is needed. To compare the time in any two or more cities, anywhere in the world, one site is the time zone converter of world clocks at: http://www.timeanddate.com/worldclock/converter.html . Here you can add about 10 cities to compare. They show the exact time & date, and take care of the UTC/GMT, EST, DST, and other technicalities. There are many other sites also that show world clocks. Some even offer free software that you can download and customize it as per your choice. But if your chosen city does not observe DST, then the above chart should work fine.
