The examples I found were similar to the ones you pasted..which show count of days between 2 dates. That is not what I'm looking for. Instead, I'm looking for time difference excluding weekends. *The closest match I found in online search washttp://searchoracle.techtarget.com/expert/KnowledgebaseAnswer/0,28962... |
Saturday or Sunday, this should do it:
date2 - date1 - 2*(trunc(next_day(date2-1,'FRI')) -
trunc(next_day(date1-1,'FRI')))/7

Assuming that date2 is the later date and that neither date falls on a Saturday or Sunday, this should do it: date2 - date1 - 2*(trunc(next_day(date2-1,'FRI')) - trunc(next_day(date1-1,'FRI')))/7 /snip |
Ken,
Thank you so much..this works perfectly.
