Understanding Time Conversion
Converting time between different time zones can be confusing, especially when dealing with large geographic distances. To help simplify this process, we present a comprehensive guide to converting from 4 AM Eastern Time (ET) to Singapore Time (SGT).
Step-by-Step Conversion:
- Determine the UTC Offset: ET is 5 hours behind Coordinated Universal Time (UTC), while SGT is 8 hours ahead of UTC.
- Calculate the Time Difference: Subtract the UTC offset of ET (5 hours) from the UTC offset of SGT (8 hours) to get a difference of 3 hours.
- Adjust for Daylight Saving Time (DST): If DST is observed in either ET or SGT during the conversion period, adjust the time difference accordingly (usually an additional 1 hour).
- Apply the Time Difference: Add the time difference (3 hours, or 4 hours with DST) to 4 AM ET to obtain the corresponding time in SGT.
Example:
If it is 4 AM ET on a non-DST day, the corresponding time in SGT would be:
4 AM ET + 3 hours (time difference) = 7 AM SGT

| Time in ET (Non-DST) | Time in SGT (Non-DST) |
|---|---|
| 5 AM | 8 AM |
| 6 AM | 9 AM |
| 7 AM | 10 AM |
