You can create more than 1 pattern in the event series e.g. A yoga class that is on Monday’s 8.30am and Thursdays 6pm

Monday’s 8.30am is first pattern, and Thursday’s 6pm is the second pattern

One you have created 1 type of recurring event, you can now create the next event series, by clicking on Add more events to create the next pattern in the series.  You can then update amend the time and day the event reoccurs e.g. Weekly, Thursday 6pm

If there is a break in the pattern e.g. a public holiday see recurring event with exclusions
