Weekday daytime

(1) Jack likes to work during the daytime.

(2) Jack likes to work during weekdays.

(1) doesn't tell you whether he works on weekdays or weekends during the daytime.

(2) doesn't tell you whether he works in the morning/afternoon or evening during weekdays.

Suppose that Jack works on weekdays and he works during the daytime. I am not sure if you can combine the two ideas into one sentence, as shown below.

(3) Jack likes to work during weekday daytime.

I hope you understand my question. If (3) is wrong, how do you say it correctly? Thank you very much for your time and help.
