Sunday and Friday are both tied so..yeah. :P
Friday is everyone gets off school and places are open late (most of them)
Sunday is just a church day and happy day so people like to share with their children or boyfriend or family member that happiness. :)
Many people are paid on Fridays and do their shopping. They are busy and go to restaurants instead of cooking at home.
Friday
according to jade cox saturday is the busiest dat
monday or friday
Sunday and Tuesday, mostly!
McDonalds in Moscow Russia
I can't say about biggest but the busiest one is in Connecticut off I-95
The busiest work day of the week is definitely Tuesday. Make no mistake about it, this day brings forth a blizzard of e-mails, phone calls, IM conversations, business conference meetings, and face time with the boss. No other day of the week has it much worse. I think it is on Monday as work will pile give by boss during weekends
While many online retailers offer deals on Cyber Monday (the Monday after Thanksgiving), the busiest online shopping day takes place on the Monday or Tuesday a week or two before the week of Christmas.
It is Saturday because the children are free from school so they ask mum to buy things for them.
The pope is always busy but, perhaps, the busiest time is during Holy Week and Easter.
Not even close... AAA says the busiest travel days are in summer months...
Friday
I would guess the weekend after Christmas.
