I am trying to create some Issue Filters in JIRA based on CreateDate.
CreateDate
The only date/time function I can find is Now() and searches relative to
Now()
You might use one of our plugins: the JQL enhancement functions - check out https://plugins.atlassian.com/plugin/details/22514
There is no interval on day, but we might add it in a next iteration, if you think it is usefull.
