Cron has been extended to support the 'last day of the month' and last week day weekday of the month.
Lets Let's recap the structure of a cron attribute:
...
Remember we *AND* across -w, -d, -m then *OR* for each element in -w, -d,-m
The new cron format will will use L, to represent the Last day of the month , or last week day weekday of the month.
Hence we now support:
- -w day of the week week. valid values are, 0 → 6 where 0 is Sunday, 1 is Monday, etc AND
0L→6L 0L→6L, where 0L means last Sunday of the month, and 1L means the last Monday of the month, etc
It is an error to overlay, i.e. cron -w 0,1,2,1L,2L,3L 23:00 will throw an exception - -d day of the month, valid values are in range 0-31,L Extended so that we now use 'L' to mean the last day of the month
- -m month valid values are in range 0-12
