Example Calculation
If you’re in Pune, Maharashtra, India (IST, UTC+5:30), and the current time is 1:00 PM on February 25, 2025:

Time Zones and Their Impact
Time zones significantly impact time calculations. For instance, if someone in New York (Eastern Standard Time, EST, UTC-5:00) performs the same calculation at 1:00 PM EST.
- Current Time: 1:00 PM EST
- Subtract 9 Hours: 1:00 PM – 9 hours = 4:00 AM
- Resulting Time: 4:00 AM EST on February 25, 2025
However, due to the time difference between IST and EST, 4:00 AM EST corresponds to 2:30 PM IST. Therefore, while both calculations result in 4:00 AM locally, the actual times differ when considering the global context.
