Nö. man crontab sagt:

Commands are executed by cron(8) when the minute, hour, and month of
year fields match the current time, and when at least one of the two day
fields (day of month, or day of week) match the current time (see
``Note'' below). cron(8) examines cron entries once every minute. The
time and date fields are:

    field          allowed values

    -----         --------------

    minute        0-59

    hour          0-23

    day of month  1-31

    month         1-12 (or names, see below)

    day of week   0-7 (0 or 7 is Sun, or use names)

A field may be an asterisk (*), which always stands for ``first-last''.

Ranges of numbers are allowed. Ranges are two numbers separated with a
hyphen. The specified range is inclusive. For example, 8-11 for an
``hours'' entry specifies execution at hours 8, 9, 10 and 11.

Lists are allowed. A list is a set of numbers (or ranges) separated by
commas. Examples: ``1,2,5,9'', ``0-4,8-12''.

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
