PostCalendar’s idea came originally from a Calendar module developed by Rob Sutton for the PHP-Nuke CMS system. Rob Sutton’s Calendar was released under GPL.

Mahmood Al-Yousif converted the Calendar to the PostNuke CMS and released it as version 1.5c (PostNuke 0.5x).

Version 1.6 was subsequently released by Mahmood Al-Yousif and it included the conversion to a “standard” PostNuke module.

Bjarne Varoystrand and Magnus Hammar modified Calendar to a much more usable system and released it under 1.62.

The PostCalendar name was introduced with version 2.0 in January 2001. The development team responsible for 2.0 were Craig Hamlin, HotBird and Mahmood Al-Yousif.

In v2.5, the same core crew of 2.0 added more features. In addition credits go to Benoit Estrade who added the concept of Start of the Week Day to Sunday/Monday - Mahmood adapted that to include Saturday which was a hugely requested feature.

Work was also done in 2.5 to convert PostCalendar to be complient with the Rogue series of PostNuke (0.7x) with basic admin authentication etc.

Version 3.0 is by far the most important release (that is not putting down the previous versions at all though).

Roger Raymond is solely responsible for series 3.x and 4.x of PostCalendar.

It was necessary to “retool” PostCalendar completely to be able to utilize the published pnAPI and modulesAPI so that PC would run on PostNuke versions 0.71+.

PostCalendar since version 3.0 is COMPLETELY legacy code free. Every line of code in there is original by [Roger|http://www.asphyxia.com] (so blame him for any screw-ups!! ;D )

Version 4.0 heralds the appearace of Templates, correct and flexible repeating events, and many other kool stuff.
