Six days(sunday to monday) you shall labor, and do all your work, but the seventh day(Saturday, which is the last day of the week) is a Sabbath to the LORD your God. On it you shall not do any work .... For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy. —Ex. 20:8-11⁠

Why are you still "observing days and seasons"? Are you still under the law? Am not!

All days of the weeks are there and can be use for worship, why restrict yourself to a single day?

Why Judge people on the basis of "days and seasons and of observant of a sabbath"?

We are christians, are you not?

And how do you use only sabbath to do this work?:

(Matthew 24:14).
"And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come. " (Matthew 24:14).

Jesus dealth with that already. We are not enslaved to it. He worked on the sabbath day . Resting the body is good . It's a matter of choice.

Mark 2:27-28
And he said unto them, The sabbath was made for man, and not man for the sabbath: Therefore the Son of man is Lord also of the sabbath.
