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:

Title Start End
Team Meeting Wednesday, September 13, 2006 9:30 AM Wednesday, September 13, 2006 2:30 PM
Appt Wednesday, September 27, 2006 12:30 PM Wednesday, September 27, 2006 1:30 PM
[edit]

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

Title Start End
Team Meeting Wed 13 Sep 2006 9:30 AM Wed 13 Sep 2006 2:30 PM
Appt Wed 27 Sep 2006 12:30 PM Wed 27 Sep 2006 1:30 PM

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.)

[edit]

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

Title Start End
Team Meeting Wed 13 Sep 2006 09:30 Wed 13 Sep 2006 14:30
Appt Wed 27 Sep 2006 12:30 Wed 27 Sep 2006 13:30

Set your operating system time date format to "HH:mm:ss".

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

[edit]

3. Display time before date, so year can be cropped.
