One Sunday - Sunny day

Hi) I guess U can say "One Sunday it was sunny" but not "One Sunday it was sunny a sunny day."
and keep in mind that expressions such as every day,nce a week etc. go at the beginning or the end of a sentence. That's why you'd say John practises football after school every day.

I mean "Once a week")

Thanks. Can I say,

(b) One Sunday it was sunny day.

P/s:... after school every day. or ....every day after school? Which is correct?

For me I think this is much better....

One Sunday, it was sunny; John practices football after school every day.

Because what are u trying to say is he practices football after when he finish his school and every day.

Thanks.

One Sunday, it was sunny; John practices football after school every day.

(can I use "practices the football..." with "the football"?)

U can't say "the football"...'cause U can't use articles before such words as Football,volleyball, tennis and so on
