Will this work with Date-time picker ?

Hi,

Why not?)

basically i try to implement it for rental system based on day(s).

i look to change price based on date(s) chosen. say for eg. if the chosen is for one day it should show 500 if the days is of 2days it should multiply and calculate it as 1000. And if the date(s) are more than 7days it should reduce the value of per day cost to 400 until 2weeks.

if this is possible share the docs link..

Notice the special variables here – you can use them in your price calculation formula.
