add_dates

add_dates adds two objects, both of which can be
  date-time objects. Lubridate is built so that you don't
  need to use add_dates but can use regular math
  expressions instead.

Lubridate makes it easier to work with dates and times by
        providing functions to identify and parse date-time data,
        extract and modify components of a date-time (years, months,
        days, hours, minutes, and seconds), perform accurate math on
        date-times, handle time zones and Daylight Savings Time.
        Lubridate has a consistent, memorable syntax, that makes
        working with dates fun instead of frustrating.
