I have a question concerning the use of prepositions.
Could you say:
"We went to the restaurant for mother´s day."
meaning "to celebrate Mother´s day" or should it simply be "on Mother´s day"?
People do say: "I bought this for her birthday" or "...for Christmas", don´t they?
To say "for Mother´s day" seems to be wrong as in "Repeat this for four times!" instead of "Repeat this four times!",but I am not sure about.
