I found these on Oxford Dictionary
Usage of Holiday:
- Holiday is used in both Britain and US to mean a single day without work because of a religious or national festival. Eg: Friday is a holiday in Muslim countries.
- Holiday is used in Britain and vacation in the US when talking about the regular period of time taken away from work each year. Eg: Where are you going for your summer holidays?
Malaysian English is according to British English. So if I were to say going somewhere for 1 day, i should say went on holiday. If it is for 3 days, then i should say went on holidays. Is my concept correct?
Well, that's Oxford's concept. Your understanding (or perhaps conception) of the concept is correct.
My sentence is as below:
Last week, Jenny went on holidays in Ipoh (Ipoh is a place in Malaysia. Should it be in Ipoh or to Ipoh?)
