I am with Blue, normally working M-F, with some semblance of banker's hours. That's the life of a fed. 
With that said, I frequently handle stuff on weekends and at nights... started 2 days last week at 3:30-4am. I have done MANY special assignments where I worked a month straight of 12 hour days with no days off.

"The difference between 'involvement' and 'commitment' is like
an eggs-and-ham breakfast: the chicken was 'involved' - the pig
was'committed'."
