Date column narrowing - Sunbird Lightning Calendar

From MozillaZine Knowledge Base

The event list displays dates using the the operating system long date format. If the day-of-week and month are fully spelled out (the default on MSWindows), the start and end columns may be very wide in some locales, such as English:

1. Abbreviate the day-of-week and month format to reduce the horizontal space needed.

Set your operating system long date format to used abbreviated day-of-week and month names, such as"ddd d MMM yyyy".

(See Configuring the date/time system settings on your computer.)

2. Use 24-hour time to further reduce the space needed.
