If your system doesn't accept text DoW denotation such as Mon, Tue, you can use numeric. In most systems, week starts from Sunday as 0. 0 0 * * 1/2 run my alert Here is from man 5 crontab Step values can be used in conjunction with ranges. Following a range with ``/<number>'' specifies skips of the number's value through the range. For example, ``0-23/2'' can be used in the hours field to specify command execution every other hour (the alternative in the V7 standard is ``0,2,4,6,8,10,12,14,16,18,20,22''). Steps are also permitted after an asterisk, so if you want to say ``every two hours'', just use ``*/2''. (Of course, my manpage also states day of week 0-7 (0 or 7 is Sun, or use names)
