NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

Converting from UTC to AM/PM
for both standard and daylight saving time

Standard Time:
When converting from Coordinated Universal Time (UTC), first use the conversion table below.


From UTC to Local Time:
Eastern Standard Time (EST) UTC - 5 hours = EST
Central Standard Time (CST) UTC - 6 hours = CST
Mountain Standard Time (MST) UTC - 7 hours = MST
Pacific Standard Time (PST) UTC - 8 hours = PST

Next, the local time is converted from a 24 Hour Clock to an AM/PM time.

Some Examples:

If the local time on the 24 hour clock is less than 0000, then you have crossed over to the previous day. So for example, -0400 becomes 2000 the day before.

Daylight Saving Time:
When converting from UTC to Daylight Saving Time, the conversions are similar but the UTC Time is one hour less than when converting than its Standard Time counterpart. First use the conversion table below.


From UTC to Local Time:
Eastern Daylight Time (EDT) UTC - 4 hours = EDT
Central Daylight Time (CDT) UTC - 5 hours = CDT
Mountain Daylight Time (MDT) UTC - 6 hours = MDT
Pacific Daylight Time (PST) UTC - 7 hours = PDT


Next, the local time is converted from a 24 Hour Clock to an AM/PM time.
