My best day is January 1, the day I got the phone
My best day gave me many gifts
Мost people's best day is a birthday because you give many gifts
The best day of my friend all had fun
For me the best day of this past vacation, I am very well rested
For my class best day is Saturday because we are going camping
I didn't like Monday until it was, for me, the best day
The best day of the entire class we rested
The best day is often a weekend or holiday, in holidays I play with my friends
I like Friday while Saturday was not the best day
