refactor: Refactor addEventsToCalendar to properly handle date validation and usage

- Updated the handling of start and end dates in the addEventsToCalendar function.
- Added validation checks directly on startDate and endDate to ensure they are valid before updating event properties.
- Improved logging for better traceability of event addition and date handling.

Note: The changes are intended to enhance the handling of date properties, but further testing is required to ensure full functionality.
