I am trying to create a Cron expression that runs every day at 8:00 AM and 3:30 PM. I understand how to create an expression that runs once a day, but not at multiple set times.

Use two lines: 0 8 * * * for 08:00 and 30 15 * * * for 15:30. Cron pairs every listed minute with every listed hour, so 0,30 8,15 would run four times.

How do you run a cron job every minute only on specific hours?

Use * 11,16,21 * * *: minute * with an hour list runs every minute during those three hours, 180 times a day. For one run per hour change the minute to 0.

How can I execute a cron job twice daily at midnight and 13:30?

Use two lines: 0 0 * * * for midnight and 30 13 * * * for 13:30. A combined 0,30 0,13 * * * fires four times a day: cron pairs every minute with every hour.

How do I set up a cron job that runs every day at 1PM, 2P… - Cron answer & example

Q: How do I set up a cron job that runs every day at 1PM, 2PM and 3PM?

Use 0 13,14,15 * * *: an hour list runs at 13:00, 14:00 and 15:00 daily. 0 13-15 * * * is the equivalent range; different minutes need separate lines.

Question

How do I set up a cron job that runs every day at 1PM, 2PM and 3PM?

Answer

Use one expression with a comma-separated list in the hour field. It runs your command at 13:00, 14:00, and 15:00 every day.

crontab

# every day at 13:00, 14:00, and 15:00
0 13,14,15 * * *

Read 0 13,14,15 * * * from left to right: 0 selects minute 0, so every run starts at the top of the hour; 13,14,15 selects the three hours in 24-hour time; the day-of-month * permits every date; the month * permits every month; and the day-of-week * permits every day of the week. Because these hours are consecutive, 0 13-15 * * * is an equivalent range form, but the list makes the requested times explicit. Lists also work for nonconsecutive hours, such as 0 13,16,21 * * *. If each run needs a different minute, for example 13:00, 14:15, and 15:30, you need separate cron expressions because cron combines every selected minute with every selected hour.

Run 0 13,14,15 * * * on Crontap

Why this matters

Combining hours in one list avoids maintaining three equivalent cron entries and keeps a shared command in one place. The failure mode appears when you also list multiple minutes: cron takes the cross-product of those fields. For example, 0,30 13,14,15 * * * runs six times, not three paired times. Use one expression only when every selected minute should apply to every selected hour; otherwise, use one line per time, as in the 8:00 AM and 3:30 PM answer.
