LocalDate

LocalDate is the workhorse of the java.time package for representing a calendar day: a year, a month, and a day of the month, with no clock time and no time zone attached. In an e-commerce app, that's the right type for an order date on a printed invoice, the day a sale starts, or the deadline by which a return must be received. This lesson covers how to build a LocalDate, how to read fields from it, how to do arithmetic with days, weeks, months, and years, and the edge cases (like month-end) that complicate hand-rolled date math.
