java.lang.Object

tech.tablesaw.columns.dates.PackedLocalDate

public class PackedLocalDate
extends Object

A short localdate packed into a single int value. It uses a short for year so the range is about +-30,000 years

The bytes are packed into the int as: First two bytes: short (year) next byte (month of year) last byte (day of month)
