List of NPC Sororities by Founder's Day Date (calendar date)

[ree-Xi]

I was wondering if anyone knew of a list of the founder's day dates of the NPC Sororities (and other inter/national orgs) in calendar order.

For example:

ABC founded January 12, 1899
DEF founded February 3, 1881
GHI founded February 25, 1903

I have Googled but I think I am not using the right search parameters. I also checked the NPC site but I didn't find what I was looking for.

I was wondering because it would be nice to have a list of perhaps all of the inter/national groups including NPC, NHPC, NIC, other National social Fraternities (don't know the other delegations), National Service orgs, etc., so that others can wish each other "Happy Founder's Day".

Any direction is appreciated.
