Saturday is my holiday, I have some free time "this day / that day" ? Which is correct?Thank you :)

Question

Answer

"I have a holiday on Saturday, so I have some free time that day."  If you use "this day", it seems to imply "today".

Saturday is a free day for the regular working Joe, so it sounds strange to call Saturday a holiday. If you normally work Saturdays, then you can simply say "I have a free day on Saturday," or "I have a day off on Saturday."

Answer

I have a day off on Saturday, So i have some free time then.
