Calendar Preferences

You can use the options under Calendar preferences to configure your calendar. 

  • Time zone - The default time zone setting is applied across all the Zoho services. You can change your time zone each time you travel to a new location and choose to get notified when your time zone is different from that of your current location.
  • Secondary time zone ​- You can add a secondary time zone to your calendar view so that you can view the events on your calendar with respect to the secondary time zone and the primary time zone as well. Once you configure your secondary time zone, both the primary and secondary time zones will appear on the time grid of your calendar.
  • Date format ​- The dates in Zoho Calendar will be displayed based on the date format chosen in the calendar settings. There are four default date formats available: MM/dd/yyyy, dd/MM/yyyy, yyyy/MM/dd, yyyy-MM-dd.
  • Time format ​- You can choose to have the standard 12 Hours or 24 Hours time format.
  • Default view - The default view represents the calendar view that you see every time you open Zoho Calendar. When you refresh the calendar, it will take you back to the default view. There are six views to choose from: Day, Week, Work, Month, Agenda, and Year views.
  • Week starts on - The first day of the week differs in certain parts of the world. You can customize the calendar and set your first day of the week in the settings.
  • Workweek - You can customize your calendar view to display the workweek based on your preference. You can choose the start and end day of your workweek in the calendar settings.
  • Work hours - You have the option to set your work hours. This helps people to look at your calendar and schedule meetings depending on your working hours.
  • Free/ busy consideration - You can choose to show yourself busy during non-working hours. Once Work Hours is set, you can enable the option to mark you busy during non-working hours in your free/ busy schedule.

Event Settings

You can set default event settings such as event duration, participant permissions, automatic addition of events to the calendar, and show/ hide denied events. These settings will be applied across Zoho Calendar.

  • Default event duration - You can set a default event duration which will be reflected in the time field of the event creation tab across all your calendars. The chosen time duration will be set by default when you create an event. You can change the duration while creating an event.
  • Default participant permissions - Participant permissions help the host of an event to limit the participant access to view, edit, delete or add participants to the event. You can set a default option in your calendar settings and that will be reflected when you create an event across any calendar. You can customize the participant permissions while creating an event.
  • Automatic addition of event invites from email - With this setting, you can restrict others from sending event invitations and creating events on your calendar without your approval, thus preventing spam. Instead, the invitations will reach your primary email address, and you can accept the invitation from the email.
  • Automatic addition of group invitations to your personal calendar You can use this setting to allow/ deny the automatic addition of group invitations to your personal calendar.
  • Show/ hide the denied/ cancelled events - If you don't want to display the denied/ cancelled events on your calendar, you can choose to show/ hide such events in your calendar grid.
