Can you gain weight over a weekend?

I've probably eaten about 600-1000 calories more than I would usually over this weekend.  Will I have gained weight?

about 1/6-2/7 of a lb maybe. but if youve been dieting for awhile you may find youll lose because of that break

You may have gained 1/3 of a pound, not bad at all. I ate about 5000 extra calories this weekend u will be fine!!

I hiked in the mountains and burned 1800 calories,(3hours of hard terrain) ate around 2300 calories a day on saturday and sunday and did drink wine and gained 5 lbs this weekend. What the hell, the food was salty and I got very thirsty when I was hiking and ran out of water, then had 6 glasses of water when we got back to the hotel. I think it is water weight but still, not fair.
