Hi Alex,
Greetings from Syncfusion Support.
Currently in scheduler we couldn’t set a time in a day as start hour and a time in next day as end hour. We have already considered this requirement as feature request and logged the below feedback.
The feature will be implemented in any of our upcoming releases. At the planning stage for every release cycle, we will review all the open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest and its importance in component. Priority will be given to feature request which has maximum number of votes. So, we request you to keep track of the status through the above feedback link.
Regards,
Vinitha
