Class RareOrImpossibleDateException

  • All Implemented Interfaces:

    public class RareOrImpossibleDateException
    extends RuntimeException
    This exception is thrown when trying to determine the previous or next occurrence of a given date determines that it's not happened, or going to happen, within some time period (e.g. within the next year).

    This can typically have a few different reasons:

    • The date is impossible. For example, June 31 does never happen, so 0 0 31 6 * will never happen
    • The date happens only rarely
      • February 29 being the obvious one
      • Cron tab patterns specifying all of month, day of month, and day of week can also occur so rarely to trigger this exception
