SAPUI5 calendar

Hello!

I try to build a timesheet for consultant in SAPUI5. An important controll is that SAPUI5 needs to have a calendar. The only one I find is the calendar textfield. I know that JQuery have a very nice calendars. Do you guys know if there is a way to implement a calendar? I have tried to implement a javascript calendar myself. But what I know SAP dont guarantee support for your own build controls if they upgrade SAPUI5. So I would like to have it directly somehow in SAPUI5.

Kind regards
