Great, works well. Can I impose on you to do it in reverse? I just don't
have the skills in Excel to reverse it. Thanks again. "49 forever" wrote: I'm trying to use Excel to make a converter between GMT and EST/EST DST. |

With EST/EDT in A1, given the current rules, then: =A1+5/24+IF(AND(A1=DATE(YEAR(A1),3,15)-WEEKDAY(DATE(YEAR(A1),3,14)) +2/24,A1<DATE(YEAR(A1),11,8)-WEEKDAY(DATE(YEAR(A1),11,7))+2/24),-1/24,0) should probably work to return UTC. --ron |
