Calculating day of the week XSL

Question

Trying to calculate day of the week number from date. Found some examples in the internet, but instead of day of the week number i see this : NaN.

Answer 1

The following stylesheet:

XSLT 1.0

when applied to your input example:

  2013-01-01
  2013-05-24
  2013-12-25
  1957-07-13
  1776-07-04

will return the following result:

25364

Note:

The main problem with your attempt is this:

Your input has dates, not date-times, and they do not contain "T".
