Also remember you can use ELisp in formulas: | Date 1 | Date 2 | Duration | |-------------------------+-------------------------+----------| | [2013-12-21 sam. 00:00] | [2013-12-22 dim. 00:00] | 86400.0 | #+TBLFM: $3='(- (org-time-string-to-seconds "$2") (org-time-string-to-seconds "$1"));L PS: note the quotes around "$2" and "$1", they are necessary so that the date is not literally inserted in the formulas when Org is computing it.
