The date module for Drupal (https://www.drupal.org/project/date) is generally brilliant and I've used it a number of times in the past. In Drupal 8 it is part of core which is testament to how useful a module it is.
The St Margaret's Church website I recently produced was a major upgrade to a previous site I had built for them. One of the sections I was quite keen to improve upon was the newsletter. The newsletter on the website was another way to distribute the newsletter which was given out each week at mass. The newsletter, called the "St Margaret's Page", was produced in MS Publisher by the parish administrator. At the time, the best way to convert it to a format for the website (reliably and quickly every week), was to save it as an image and then allow it to be viewed in a lightbox.
A bit of a re-brand, new responsive metro-ish design and completely re-built on Drupal 7. I've been planning it for a while, but have finally found the time to complete it.
