Perpetual date

[Lukester]

I am noob in rolex watches. I want to know what does perpetual date mean in Rolex watches? Does it function like a perpetual calendar in some other brand of watches?
What about date just? What does it mean?
Thanks!

Datejust means just the date is displayed... Daydate is displaying both the day and date...
