If you have an event that happens on a recurring schedule, it's easy to add. Just use our recurring event feature. 

First, you need to save the event. Just use the first date of the event as the event date.  Once you save the event, you will be on the event detail page. 

Next, under the "Dates" section of the page, you will notice an orange "Convert to Recurring" button. Click that button to change the existing event into a recurring event. 

You will be presented with a Convert to Recurring Dialog window. Here you can select who often you would like the event to recur: daily, weekly, monthly or yearly. You can also select how often is recurs, for example, every 2 week, every 3 days, every 2nd month. Specify the date is starts when it ends (or never) and which days it recurs on. 

There is also advanced functionality to exclude specific days from the recurring schedule.  For example, Karaoke night every Wednesday in December except the 24th and 25th because you're closed.

You can create very confusing schedules, like the 1st and 3rd Tuesday of every week except the 4th of July. Site visitors don't see your complexity, but a simple, easy-to-read list of dates.

Have fun with the recurring schedule even for your most complex tasks, I'm sure you'll be able to easily add even the most complex recurring schedule. 

You can even edit recurring schedules easily and all the dates will reconfigure for you, without a calendar mess.
