YOU SAID:
I am going to celebrate my mom's birthday
INTO JAPANESE
私は私の母の誕生日を祝うつもりです
BACK INTO ENGLISH
I will celebrate my mother's birthday
INTO JAPANESE
母の誕生日を祝います
BACK INTO ENGLISH
Celebrate Mother's Birthday
INTO JAPANESE
母の誕生日を祝う
BACK INTO ENGLISH
Celebrate Mother's Birthday
That didn't even make that much sense in English.
