Date calculation

Hello.

I am using your plugin and wanna know, is it possible to make date calculations?

I am trying to create a booking form and it consists two date fields:

Date of arrival and last date of visiting. I have price per day, so I want your plugin to calculate the difference between last and first dates and multiply the number of days on the price per day.

Also can your plugin use “month” from date as a condition to use particular price. So each month will have its own price per day and if person comes in august it is one price, if in september it will be another.

For example, user arrives at 12.08.2019 and leaves at 20.08.2019. Your plugin automatically calculates that it is 8 days and multiplies it to the price per day which is set for august. That will help client understand approximate price of renting.

Can I make this calculations with your plugin or may be you know how to do them in another way using your plugin?
