Time Zone Converter

Convert a time between any two time zones.

Overview

Converts meeting times across worldwide international time zones, calculating UTC offsets, military time, and Daylight Saving Time (DST) shifts.

Formula & Calculation Method

Target_Time = UTC_Time + Target_Timezone_Offset (accounting for active DST)

Converts between IST (UTC+5:30), EST/EDT (UTC-5/-4), PST/PDT (UTC-8/-7), GMT/BST (UTC+0/+1), and Australian time zones.

Worked Example: 7:00 PM Indian Standard Time (IST) to US Eastern Time (EDT)

Inputs: Source Time = 7:00 PM IST (UTC+5:30) | Target Zone = US Eastern Daylight Time (UTC-4:00)

  • Calculate total time difference: (+5:30) - (-4:00) = 9 hours and 30 minutes
  • Subtract difference: 7:00 PM IST - 9 hours 30 minutes = 9:30 AM EDT (Same Day)

Summary: 7:00 PM IST = 9:30 AM US Eastern Time (EDT) | Time Gap = 9.5 Hours Behind
