Category:Projects by timeframe
Many projects are categorized by their completion date. Please see the dated subcategories below for projects completed in a given time-frame.
Guidelines for using the date categories
If a project is to be categorized by time (not necessary), it should be categorized by the first completion date (if a project was completed in the past, use the date it was completed.. not the date it was added to Appropedia). If much time has passed and a significant update has been made, a project can be categorized under that date as well. As more projects are added to Appropedia, it is possible that months may be prefixed to the year, such as Category:January 2008.
