I know the Jewish sabbath is Saturday. Many Christians worship on Sunday. Is there a right or wrong day to worship. Jesus said rest on the sabbath. But Paul had church on Sunday(first day of week). So witch one is right or wrong or it doesn't matter. Please provide biblical proof for points.

There is no absolute right or absolute wrong about Saturday or Sunday worship. The church you attend will have services on one of those days. I am sure if you ask your pastor or priest or minister, they would be more than glad to sit down and discuss this with you.

Here are some net articles on the Saturday vs Sunday worship:

Col 2:16-18
16 So let no one judge you in food or in drink, or regarding a festival or a new moon or sabbaths, 17 which are a shadow of things to come, but the substance is of Christ.
NKJV

My church has services on both.

I may also wonder where we have Paul having , church, on sundays, paul regularlly meet in the jewish temples and taught there, but he preached and taugh on every day of the week any and every time someone would listen.

Saturday is the true sabboth, a day of rest, so rest on Saturday, but this is part also of the new testement where we are not under the law of the old testement

Sunday is today considered a day of recreation. But through the centuries, we have lost the meaning of those words. To most people, recreation means fun and pleasure. But that is not the original meaning. To re-create, is to create anew.

That is the reason for the Sabbath being replaced by our Lord's day.

Our Lord is the New Adam and the New Testament times is the New Creation by grace. Our Lord fulfilled the Old Testament in every way. He is the first fruit of all creation and was raised from the dead on the Jewish Feast of the First fruits.

And although Christians celebrate the Passover every day instead of once a year, even in Biblical times, Christians were already meeting on Sunday rather than Saturday for their obligatory meeting:

Acts Of Apostles 20

7 And on the first day of the week, when we were assembled to break bread, Paul discoursed with them, being to depart on the morrow: and he continued his speech until midnight.

1 Corinthians 16

2 On the first day of the week let every one of you put apart with himself, laying up what it shall well please him; that when I come, the collections be not then to be made.

So, to answer your question, as Christians we do not worship just on Saturday but everyday, but Jesus Christ fulfilled the Old Testament and the New Obligatory day of worship is Our Lord's day, Sunday, the first day of the week.

2190 The sabbath, which represented the completion of the first creation, has been replaced by Sunday which recalls the new creation inaugurated by the Resurrection of Christ.

Sabbath is meant as rest from working, a day to focus on the LORD. I try to focus on Him everyday, not just one.
