Cron for the 15th of Every Month

0 9 15 * * breaks down as: minute = 0; hour = 9; day-of-month = 15; month = *; day-of-week = *. Because the day-of-week field is left as * here, there's no OR-logic ambiguity to worry about — see the first Monday of the month page for the pattern where that ambiguity does matter.
