11.4.2 Time-of-day specifications

Org mode checks each agenda item for a time-of-day specification. The time can be part of the timestamp that triggered inclusion into the agenda, for example

<2005-05-10 Tue 19:00>

Time ranges can be specified with two timestamps:

<2005-05-10 Tue 20:30>--<2005-05-10 Tue 22:15>

In the headline of the entry itself, a time(range)—like ‘12:45’ or a ‘8:30-1pm’—may also appear as plain text1.

If the agenda integrates the Emacs diary (see Weekly/daily agenda), time specifications in diary entries are recognized as well.

For agenda display, Org mode extracts the time and displays it in a standard 24 hour format as part of the prefix. The example times in the previous paragraphs would end up in the agenda like this:

 8:30-13:00 Arthur Dent lies in front of the bulldozer
12:45...... Ford Prefect arrives and takes Arthur to the pub
19:00...... The Vogon reads his poem
20:30-22:15 Marvin escorts the Hitchhikers to the bridge

If the agenda is in single-day mode, or for the display of today, the timed entries are embedded in a time grid, like

 8:00...... ------------------
 8:30-13:00 Arthur Dent lies in front of the bulldozer
10:00...... ------------------
12:00...... ------------------
12:45...... Ford Prefect arrives and takes Arthur to the pub
14:00...... ------------------
16:00...... ------------------
18:00...... ------------------
19:00...... The Vogon reads his poem
20:00...... ------------------
20:30-22:15 Marvin escorts the Hitchhikers to the bridge

The time grid can be turned on and off with the variable org-agenda-use-time-grid, and can be configured with org-agenda-time-grid.

  1. You can, however, disable this by setting org-agenda-search-headline-for-time variable to a nil value.↩
