The default time format for the core Calendar block depends on the locale, but you can customize it using a custom block template. In the custom block template you can add a timeFormat property option with the time format you prefer.

Steps to customize the default calendar time format:

  • copy view.php
  • navigate to application\blocks and create a folder called "calendar"
  • inside the "calendar" folder, create a folder called "templates"
  • paste view.php into the "templates" folder
  • rename view.php to "custom_time_format.php"
  • open custom_time_format.php and look for the .fullCalendar() method call
  • directly below the .fullCalendar() method call, paste in the timeFormat: 'hh:mma', option and value
  • after pasting the timeFormat option and value, the top portion of the .fullCalendar() method call should look like this

        timeFormat: 'hh:mma',
        header: {
  • you can now apply the "Custom Time Format" custom block template to your Calendar block to display the custom time

Example time format values:

timeFormat: 'H(:mm)', // 22:30 or 23  
timeFormat: 'h(:mm) t', // 10:30 p or 11 p  
timeFormat: 'h(:mm)t', // 10:30p or 11p  
timeFormat: 'h:mm', // 10:30 or 11:00  
timeFormat: 'hh:mma', // 10:30pm or 11:00pm  
timeFormat: 'hh:mm a', // 10:30 pm or 11:00 pm  
timeFormat: 'hh:mmA', // 10:30PM or 11:00PM  
timeFormat: 'hh:mm A', // 10:30 PM or 11:00 PM  

Setting a timeFormat property option will affect all views.

The time format can also be set on a per view basis.
