No Record of Jesus Keeping the Sabbath After His Resurrection

Jesus kept the Sabbath because He was born a Jew and under Jewish law. When He died and rose again, ushering in the New Covenant, according to the Bible He was on earth 40 days after His resurrection  before His ascension. 

Under the New Covenant, God changed the 7th day of rest to TODAY.  Hebrews 4:4-9 

4 For somewhere he has spoken about the seventh day in these words: "And on the seventh day God rested from all his work." 5 And again in the passage above he says, "They shall never enter my rest." 6 It still remains that some will enter that rest, and those who formerly had the gospel preached to them did not go in, because of their disobedience. 7 Therefore God again set a certain day, calling it Today, when a long time later he spoke through David, as was said before: "Today, if you hear his voice, do not harden your hearts." 8 For if Joshua had given them rest, God would not have spoken later about another day.
 
According to the above text, the first day God set for rest was the 7th day, then God AGAIN set a certain day, calling it TODAY. 

After Pentecost, the new believers worshiipped DAILY.  Acts 2:46 reads... 

42 They devoted themselves to the apostles' teaching and to the fellowship, to the breaking of bread and to prayer. 43 Everyone was filled with awe, and many wonders and miraculous signs were done by the apostles. 44 All the believers were together and had everything in common. 45 Selling their possessions and goods, they gave to anyone as he had need. 46 Every day they continued to meet together in the temple courts. They broke bread in their homes and ate together with glad and sincere hearts, 47. being saved those who were daily and enjoying the favor of all the people. And the Lord added to their number  praising God. (emphasis mine)  

My question is: Why is there no record of Jesus keeping the 7th day Sabbath after His resurrection? During the forty days He was on earth, it is recorded that He spoke with a group of about 500, He visited with His eleven disciples, He visited James, etc. but no record of Him keeping the weekly Sabbath; no record of Him even entering the synagogue. Is it possible that 'TODAY" became effective upon His resurrection? 
If we are to follow His "example" in all things, why not this? 

Just wondering.
