Need Help on Date Calculation

hi ,

i need your big help on calculation over date. 
1st : i'd like to calculate if the user fills arrival date in cambodia today , Departure date should show next day onward ( Can't fill the previous date less than arrival date )

2nd : If they check in Today , i'd like check out date on the next day onward. the users can't fill the previous date. 

3rd : this one too , if they fill the date of passport issue today , the date of passport expired should be next day onward. 

I am working on your condition requirement and will get back to you soon.
