Hi Nabran,
Thanks for contacting Syncfusion Support.
On validating based on the shared images, we suspect that the reason for the reported problem is while retrieving and binding the appointment data with “dd/MM/yyyy” format. In the client-side, when the date with “dd/MM/yyyy” format is processed by new Date(), the invalid date conversion happens and to get rid of this problem, we suggest you to make manual date conversion at server-side code behind from the “dd/MM/yyyy” format to “MM/dd/yyyy” format before binding it to the scheduler dataSource. Otherwise, the date conversion might result in incorrect date time values misplacing date and month values in the dates.
Regards,
M. Vinitha devi.
