module duplication?

Although similar in intent (displaying things from the past), these modules do not duplicate functionality.

The On This Day module uses the site's existing content nodes, such as blog nodes, for its content. It uses the node creation date for selection. It would display something like: On this day in previous years Fred blogged this, this and this.

The This Day in History module has it's own Historical event node type, allowing the entry of specific historical events. It would display something like: Dr. Roberta Bondar becomes the first Canadian woman in space on Space Shuttle mission STS-42 in 1992.
