Question about cron jobs

with the cron format

* * * * *
| | | | | |
| | | | |
| | | | +---- Day of the Week (range: 1-7, 1 standing for Monday)
| | | +------ Month of the Year (range: 1-12)
| | +-------- Day of the Month (range: 1-31)
| +---------- Hour (range: 0-23)
+------------ Minute (range: 0-59)

my question is on the day of the month, what if cron is setup to
use 31, what will happen if the month let us say February or any other
month that only has 30 days? Will cron run of these months?

NAME
holidays - prime/nonprime table for the accounting system SYNOPSIS
/etc/acct/holidays DESCRIPTION
The /etc/acct/holidays file describes which hours are considered prime time and which days are holidays. Holidays and weekends are con- sidered non-prime time hours. /etc/acct/holidays is used by the accounting system. All lines beginning with an "*" are comments. The /etc/acct/holidays file consists of two sections. The first non-comment line defines the current year and the start time of prime and non-prime time hours, in the form: current_year prime_start non_prime_start The remaining non-comment lines define the holidays in the form: month/day company_holiday Of these two fields, only the month/day is actually used by the accounting system programs. The /etc/acct/holidays file must be updated each year. EXAMPLES
Example 1: Example of the /etc/acct/holidays file. The following is an example of the /etc/acct/holidays file: * Prime/Nonprime Table for the accounting system * * Curr Prime Non-Prime * Year Start Start * 1991 0830 1800 * * only the first column (month/day) is significant. * * month/day Company Holiday * 1/1 New Years Day 5/30 Memorial Day 7/4 Indep.
