Monthly Cron Syntax Guide

Day-of-Month Syntax

Use the third field to specify the day of the month (1-31):

0 0 D * * - Run at midnight on day D of every month
0 0 1-7 * * - Run every day during the first week of the month
0 0 1,15 * * - Run on the 1st and 15th using comma-separated lists

Month Field for Quarterly/Annual

Combine the day and month fields for quarterly and annual schedules:

0 0 1 1,4,7,10 * - Quarterly: 1st day of Jan, Apr, Jul, Oct
0 0 1 1 * - Annual: January 1st only
0 0 1 JAN,APR,JUL,OCT * - Month names (JAN-DEC) can replace numbers (1-12)

Handling Different Month Lengths

Important considerations for monthly scheduling:

  • February has only 28 days (29 in leap years) - days 29-31 will be skipped
  • Use the 28th as a safe "last day of month" alternative that works every month
  • April, June, September, and November have 30 days - day 31 will be skipped
  • Standard cron has no native "last day of month" syntax (some implementations support L)
