Formula to Convert EST to PST (Subtract 3 hours):

=A1 - TIME(3,0,0)

Just change “3” to match the time difference for other zones.

3. Convert Time Zones Manually (Old-School Method)

If you like doing things the traditional way:

1. Find the time difference between the two zones.
2. Add or subtract the difference from the original time.
3. Adjust for Daylight Saving Time (DST) if necessary.

Example: Converting New York (EST) to London (GMT)

• EST is 5 hours behind GMT.
• If it’s noon EST, add 5 hours → 5:00 PM GMT.

Common Time Conversion Mistakes (And How to Avoid Them)

1. Daylight Saving Time (DST) Confusion

• Some regions use DST, others don’t.
• Always check if DST is active before converting.

2. Half-Hour Time Zones (Yes, They Exist!)

• Not all time zones are neat one-hour differences.
• Example: India Standard Time (IST) is GMT +5:30.

3. 24-Hour vs. 12-Hour Formats

• Some countries use 24-hour clocks instead of AM/PM.
• 14:00? That’s 2:00 PM.
