The Sabbath day for Peter was the seventh day of the week, the same sabbath day that Jesus kept and the other apostles. In Acts 16:13 we read that Paul went to the riverside on the sabbath day to pray to God. He wanted to retreat from the city and be in a quiet place with God on the sabbath. Thus showing that the apostles still kept the seventh day sabbath as per the 4th commandment.
