In my country, the standard work-week begins on Sunday and ends on Thursday with weekends being Friday and Saturday. How can I customize my week view?
With Zoho Calendar, you can decide how your work-week should be displayed. You can change the start and end days of your work-week to suit your country's work-week standard. To change your work-week, go to Settings > Calendar > Calendar view and change the start and end days of your work-week. After customizing this option, you can get back to your calendar and change your calendar view to "Work".
