in the holiday 和on the holiday 有啥区别？

in holiday 泛指放假，但说话人说话的时候并不在放假。
如，i'd like to stay with my families in holiday.

in the holiday 指特定的假期，根据上文的延续。
如，Christmas is a spcial holiday in western countries. In the holiday, people usually stay with their families.

on holiday 处于放假的状态
如，i'm on holiday now.类似有on duty 上班中

另外补充一下，如果你前面曾经提起过某个节日，而现在针对这个节日说on，就要用on the holiday,特指在这个节日。否则，用on holiday.
