Acts 2:46 hints that the early Christians celebrated the Lord’s Supper very frequently - "Every day they continued to meet together in the temple courts. They broke bread in their homes..."

Acts 20:7 says - "On the first day of the week we came together to break bread." - in other words on Sunday.

And that is what we do - meeting every Sunday, usually at the end of the morning service. On the first Sunday of the month the Lord’s Supper is held in the evening and occupies the whole service. This is a special opportunity for praise and worship and usually several people take part.
