How do I read the UTC offset in parentheses?
UTC offsets (e.g., UTC+05:30) show the time difference from Coordinated Universal Time. Positive offsets are ahead of UTC (east), negative are behind (west). For example, India (UTC+5:30) is 5 hours 30 minutes ahead of UTC.
What is the time difference between India and the US?
India Standard Time (IST, UTC+5:30) is 9.5 hours ahead of US Eastern Time (ET, UTC-5) and 12.5 hours ahead of US Pacific Time (PT, UTC-8). During DST, the difference reduces by 1 hour: 9.5 hours ahead of EDT and 12.5 hours ahead of PDT.
What is the time difference between London and New York?
London (UTC+0 GMT / UTC+1 BST) is 5 hours ahead of New York (UTC-5 EST / UTC-4 EDT). Both observe DST simultaneously, so London remains 5 hours ahead year-round.
