Weekday conditions allow you to create triggers for certain days of the week, and in particular, on certain days of the month. This allows you to trigger, for example, every Monday, Wednesday, and Friday; or every second Sunday of each month. Simply select the days of the week on which the condition should be true, and select the ordinal for the day, which is "Every" by default, but can also be one of "First", "Second", "Third", "Fourth", "Fifth" or "Last".
System Clock Dependency
If your logic relies on accurate time, please see make sure your Reactor host system is running an NTP or similar client to synchronize time to a reliable source. The built-in clocks on some systems can vary wildly over relatively short periods if not properly disciplined.
