If you need to navigate to a specific date in the Scheduler, you could use the date() method.
This method gets/sets the current date.
On the enclosed Dojo example
, on a button click the date of the Scheduler is changed.
I am afraid that currently there is no configuration which allows to start the months in 'timelineMonth' view from a date different than the 1-st of each month. I would suggest you to log it as a new feature request in our Feedback Portal.
This way other users could vote for the it. The popular requests are considered for future implementation.
