Holidays and Observances
Alphabetical Listing of Holidays

Below, you can find a Holidays and Observances Alphabetical Listing (Page 1) of US Holidays and World Holidays and Observances. Page 1 includes Holidays starting with A.  Originally we had our Alphabetical Listing on two pages, but with over 4,000 Holidays and Observances, we finally had to break the pages down by letter. We are still adding names to the list, so more information will be coming. 

After we complete the summary pages on the site, we will start working on a detailed page(s) for each Holidays and Observance. Once a page is completed for each Holiday or Observance, it will be linked up below, as well as it's related Daily Holidays page. (that should keep us busy for the next 20 years or so!!)

Adopt a Dog Month and Adopt a Shelter Dog Month are both observed in the Month of October! This beauty is Leedo who was found in an alley, alone and hungry and terrified of everything and everyone, especially men. Rescued by my daughter!
