[07:47:08] <anev>	 FoxT: What would a query look like for 'Modification date'?
[07:47:53] <anev>	 FoxT: got it with "| ?Modification date"
[07:49:49] <anev>	 weird, i had been trying "Creation date" as per https://www.semantic-mediawiki.org/wiki/Help:$smwgPageSpecialProperties where it also states "Modification date" .. not sure why one works and the other doesn't
[07:50:09] <anev>	 must double check the version i'm using
[20:20:39] <FoxT>	 anev: I did not even know about that setting! :o
[20:21:41] <FoxT>	 What you need to do to make it work is pretty easy:
[20:22:22] <FoxT>	 1. Add this to your LocalSettings.php: $smwgPageSpecialProperties[] = '_CDAT';
[20:23:07] <FoxT>	 2, Go to your MW installation directory and run: php maintenance/update.php
[20:23:46] <FoxT>	 3. Then run: php extensions/SemanticMediaWiki/maintenance/rebuildData.php
[20:23:59] <FoxT>	 This last one will take a while.
[20:24:30] <FoxT>	 When it is finished you can query for creation date like this: {{#ask:[[Creation date::>01-01-2017]]|format=count}}
[20:24:43] <FoxT>	 This should give you the number of pages created this year
