Go to your calendar and click on "Entry To Be Recurred"

The Recur Entry editor will open.
Method 1 - (suited for regular entries): Click Select Interval

Choose the interval period - For the same entry every week select "Recur Weekly" 

Enter no. of repetitions then hit "Preview Dates"

A list of dates will appear in the preview panel below, if it all looks correct click on "Apply List to Selected Dates"

Next to the DatePicker, the dates of the entries to be created wil show here. If all looks good, hit the button titled "Create Entry Series"

Your calendar will now show the new dates generated. Click on one of these newly created "recurred" entries.

Click the eye icon (or title of the entry) to view the entry.

If you made a mistake, or just wish to remove the newly recurred entries (but not the parent), click on "Delete Linked" button.

Those entries have been removed, yet the original remains. 
Let's try an alternative way. Click on "Entry To Be Recurred" and get back to the Recur Entry Editor.

These entries will not be regularly spaced so we can select directly in the datepicker. Click on any date, here we select "6th Dec"

Do the same on other dates you wish to recur this entry on, then click on "Create Entry Series"

Amazing!, all entries will have been created where specified. - We're all Done 🚀
