You did not say what OS its for. cron is implemented differently on linux v.s. Std UNIX systems

What does your man crontab say about step values? Mine says
Quote:
Step values can be used in conjunction with ranges. Following a range with ``/<number>'' specifies skips of the number's value through the range.
So - 0/2 wouldn't work.

And, looking again at it, that wouldn't satisfy your logics either. Day-of-week 0-7/2 would mean Sunday, Tuesday, Thursday, Saturday .

Use 0 and discriminate every other Sunday within the script.
