RecurrenceRule: Does it store the start and end dates of the event?

No, it doesn't. The start date can be used when creating a new RecurrenceRule instance to read certain values for the rule - e.g. day of week in case of weekly recurrence, day of month in case of monthly recurrence...

But it is not stored in the serialized rule string.

Anyway, you should be able to read the start and end date from the master record.

You can debug the recurrence rule by printing the ToJson() value - it returns a readable string with all values that are stored in the recurrence string.

Dan and Team,

I could reference the master record - however, if the master record start date and end date had been modified, specifically for that single occurrence, I could not.

Thanks for the information though, just means that the initial start date and end date will have to be recorded in the database for recurring events - I guess that that was the reason for storing the occurrence start date (and now end date too).
