Recently a need was identified to create a calendar using SharePoint/Microsoft Lists as a datasource. Normally, this would be an easy undertaking as you would simply create a column for start date and a column for end date. As most of us know, nothing is as simple as it ever seems. The business requirement was that an application should be created that limits the number of bookings that can be created in a day (due to covid and social distancing guidelines) and recurring dates are a must. Restricting the number of bookings was easy and to an extent recurring events was simple until it came to creating logic for recurring events on a weekly basis. With a little help from different examples in the community, I was able to find a way to set up recurring events while using SharePoint/Microsoft Lists as a data source.
