How do I run an automation once per year?

[Sonja Altmann]

Hey all.
I'm new to automations.  I want to run an automation on a specific date 15 March every year (regardless of the day of the week) .

I think I will need to use a cron expression but it comes up with an (Unexpected end of expression)  What have I missed?

30 8 15 3 *

In my head it should return 8:30am on the 15 March in any year.

Thanks for your help :)

Hi @Sonja Altmann, you might try this:

0 30 8 15 3 ?

It should be accepted by Automation "cron checker". 

In this article cron in Jira is explained, and it contains this table

Seconds (in front) needs to be specified. In the document I linked to there are some examples, like this one

Which is close to your requirements. Trying this example throws a more descriptive error though, as you see here

Using instead this "0 0 1 1,15 * ?" gives no error for that example.

Hello @Sonja Altmann 

You can find a variety of cron generating web pages to help you construct the expression. Here is one such page:
