The following setting display the date in Gregorian calendar in the mode line.
(setq display-time-day-and-date t) (display-time)
My question is how to change the above settings for date to be shown in the Julian calendar?
You can compute arbitrary date strings by overriding
The documentation says this:
List of expressions governing display of the time in the mode line. For most purposes, you can control the time format using `display-time-format' which is a more standard interface.
This expression is a list of expressions that can involve the keywords
seconds, all numbers in string form, and
time-zoneall alphabetic strings, and
For example, the form
'((substring year -2) "/" month "/" day " " 24-hours ":" minutes ":" seconds (if time-zone " (") time-zone (if time-zone ")") (if mail " Mail" ""))
would give mode line times like `94/12/30 21:07:48 (UTC)'.
To display the Julian date as provided by
calendar try this:
(require 'calendar) (setq display-time-string-forms '((calendar-julian-date-string))) (display-time)
