What I intend to say is that we cannot condemn a gathering of saints who breaks bread on other days along with or except on Sundays because the Bible is silent on the matter (that is the Lord's table must be celebrated on Sunday only).
Many assemblies in the gulf have "changed" the stated tradition (Acts 20; 1 Corinthians 11-16), observed and followed by the Apostles. Will we condemn them? It won't be safe to say that that is an exception since there is no exception to anything when it comes to doing sin. Also don't forget the "traditions" which are not convenient for us: Acts 2:44-45 And all that believed were together, and had all things common; And sold their possessions and goods, and parted them to all men, as every man had need.
Personally I will break bread every Sunday and I am open to breaking bread on other days also. But I will not condemn anyone who partakes of the table on other days. If he asks me to quote the instruction from the Bible, I will be speechless not able to show a verse that instructs "to keep" the practice. But I will have a question in my mind that if circumstances are fine with breaking of bread on sunday, why they do not do it on a sunday itself. But I am not in a position to judge and condemn.
There are a few apostolic instructions or practices which I can think of which we do not follow (eg: James 5:14 - Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord) but these can only be understood if we rightly divide the word.
You said "But they gatherd together the church more than 5000 in the temple for worship and hearing sermon of appostles in every Lord's day . "
The Lord's day which you maybe referring to Sunday is not mentioned in the passage. It could also mean that they daily were in the temple and broke bread in the house daily also (continued daily...breaking bread from house to house). This is just another interpretation to the passage
