Hello Dhara,
thank you for your quick response. Still not working well. Please find below link to printscreen from different pages, as your request.
Time zone is set OK.
Is very strange. Now I can select today date (17th)for delivery, even I put 8 hour for prepare delivery. But colour for 17 on calendar is yellow, not green
