Working with dates is something landlords and property managers do a lot.

For example, you want to increase the rent 60 day from the coming Monday.  Working out what date that is can be quite time consuming, and normally ends up with you and a calendar, counting the days.

So a new Date Add calculator is being created.  You enter in the start date, and then choose to either add or subtract a specifyed number of days, weeks or months, and RentMaster will calculate the end date for you.
