This plugin provides the daily or hourly prayer guides for the 40/40 Prayer Vigil (English) and 40/40 Campaña de Oración (Español).
This plugin utilizes a web service from DJS Consulting (http://services.djs-consulting.com/FortyForty) to display the current day or hour's suggested prayer guide for the 40/40 Prayer Vigil. The "40/40" part means that you can pray for either 40 days or 40 hours. For days, the 2012 vigil runs from September 26th through November 4th; for hours, it runs from 4pm on November 2nd through 7am on November 4th.
This plugin utilizes your blog's local date/time to display the current guide as the vigil is proceeding. It caches the results, so there should be next to no extra work for the page displays on your blog. You can select the language, the version that is used for the Scripture links, and the number of days before and after the actual vigil that the widget will be displayed.
