The recur feature allows you to periodically set a calendar entry, event, task or payment entry according to your selection.
The feature does not limit to period setting, in fact you can duplicate on any date selected should you wish to do so.
Entries created via the recur method all become individual entries so they cannot all be modified at once. However, if you have made an error during creation, there is a way to delete the created entries (with the parent entry untouched). Simply open one of the child entries and there will show a "Delete Linked" button.
For clarification and example, follow along the guide below.
