Q<integer>H every <integer> hours every <integer> hours 2.4
Q<integer>J<day#> repeats on a particular day of the week repeats on a particular day of the week 2.4 from the French jour (day). If <integer> is missing, the repeat rate is assumed to be 1. Day numbers are counted from 1=Monday to 7=Sunday. So Q2J2 means every second Tuesday; Q1J6 means every Saturday.
