How cron syntax works
A standard cron expression has five fields, separated by spaces.
| Minute | Hour | Day of month | Month | Day of week |
|---|---|---|---|---|
| 0 - 59 | 0 - 23 | 1 - 31 | 1 - 12 | 0 - 6 (Sun-Sat) |
*Any value* * * * * — every minute
,Value list separator0 9,17 * * * — at 9 AM and 5 PM
-Range of values0 9-17 * * * — every hour 9 AM–5 PM
/Step values*/15 * * * * — every 15 minutes
?No specific value (Quartz)0 0 12 ? * MON
LLast (day of month/week)0 0 L * ? — last day of month

When to use this schedule
Standard 5-field cron has no built-in 'last day' operator. Running on the 28th is the safest approximation since every month has at least 28 days. For a true last-day trigger, use Quartz cron (0 23 L * ?) or a script that checks if tomorrow is the 1st.
