When God gave the Ten Commandments on Mt. Sinai here is what He said when He gave the commandment about keeping the Sabbath day:
Exodus 20:
[11] For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested on the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
Applying the "Day-Age" theory to this passage renders it meaningless. God is instructing the Israelites to keep the Sabbath, a literal 24-hour day. He tells them why in verse 11: because He created the earth and everything in it in six days and rested on the seventh.
If the "days" of Genesis 1 and 2 are really ages or epochs than God would have been telling the Israelites to work for six epochs and rest on the seventh epoch.
To 'Israel'......enjoy your 4th Commandment!
