How can you configure a Scheduled Job to run on the last day of every month?

To configure a Scheduled Job in ServiceNow to run on the last day of every month, setting the Run field to Monthly and the Day field to 31 is the most effective approach. This configuration leverages the way scheduling works within the ServiceNow platform; when set to run on the last day of the month, it will execute correctly for months with fewer than 31 days, such as February.

If the month has 31 days, it will execute on that day. For months with only 30 days or February, the system recognizes that the last day is actually the last available date of the month, allowing the job to trigger appropriately without manual intervention. Thus, this configuration ensures reliability for every month.

On the other hand, setting it to weekly on the last day doesn't provide the needed flexibility required for months with fewer than 31 days, and using daily with a condition adds unnecessary complexity. Setting it to bi-monthly on the 31st is not suitable as it doesn't cater to the variability of month lengths, leading potentially to missed executions on relevant last days.
