I won't even begin to explain how we keep passover..

We start about 4 weeks before the festival cleaning every single inch of the house so there are no crumbs (think kids toys, pockets, everything), we pack away all our dishes and bring out new ones.. Um, we use up all our food which has leavened products in it (just about everything, i kid you not), re-kosher the kitchen, cover ever surface etc etc.

Bath - our festivals aren't really liek the Christian ones in terms of presents/foods. When we say festivals it means there are restrictions like the sabbath on us, we spend most of the day in synagoge, none of them involve presents (although on one of them you give presents to others and poor people)... They are to do with you and G-D, all about prayer and developing your relationship. We do have a festival meal, but its not like an all out thing.

Our holiest day is Yom Kippur (day of atonement), where you fast for 25 hours, not bath etc, pray basically the whole day (there is a break for maybe 1.5hrs during the day..) it's all about removing yourself from the physical.
