National Bill of Rights Day
December 15, 2015 in the USA
Bill of Rights Day is observed on December 15, 2015. The Bill of Rights is the collective name for the first ten amendments to the United States Constitution. Proposed to assuage the fears of Anti-Federalists who had opposed Constitutional ratification, these amendments guarantee a number of personal freedoms, limit the government’s power in judicial and other proceedings, and reserve some powers to the states and the public.
The amendments were introduced by James Madison to the 1st United States Congress as a series of legislative articles. They were adopted by the House of Representatives on August 21, 1789, formally proposed by joint resolution of Congress on September 25, 1789, and came into effect as Constitutional Amendments on December 15, 1791, through the process of ratification by three-fourths of the states. The Bill of Rights had little judicial impact for the first 150 years of its existence, but was the basis for many Supreme Court decisions of the 20th and 21st centuries.

Esperanto Day 2015
December 15, 2015 in the World
Esperanto Day, also called Zamenhof Day, is celebrated on December 15, 2015. The 15th December is the birthday of Esperanto creator L. L. Zamenhof. It is the most widely celebrated day in Esperanto culture. Esperanto is the most widely spoken constructed international auxiliary language. The first book detailing Esperanto, the Unua Libro, was published on July 26, 1887.
Estimates of Esperanto speakers range from 10,000 to 2,000,000 active or fluent speakers, as well as perhaps a thousand native speakers, that is, people who learned Esperanto from birth as one of their native languages. Many Esperanto speakers buy an extra Esperanto book around Zamenhof’s birthday. There are also special Esperanto gatherings and parties throughout the world to celebrate the occasion, which is used as a reason for Esperantists to get together during the holiday season.
Some Esperanto speakers, not wanting to over-celebrate the achievements of a single man, have suggested celebrating 15 December as Esperanto Literature Day instead Zamenhof Day. Thus they encourage Esperanto organizations that hold gatherings on that day to add a book review or poetry reading to the program or to announce the publication of a new book. On an individual level, one can buy or start reading a new book or in some other way celebrate Esperanto literature.

National Lemon Cupcake Day
December 15, 2015 in the USA
National Lemon Cupcake Day is celebrated on December 15, 2015. A lemon cupcake is a small lemon cake designed to serve one person, which may be baked in a small thin paper or aluminum cup. As with larger cakes, icing and other cake decorations, such as sprinkles, may be applied.
A standard cupcake uses the same basic ingredients as standard-sized cakes: butter, sugar, eggs, and flour. Nearly any recipe that is suitable for a layer cake can be used to bake cupcakes. Because their small size is more efficient for heat conduction, cupcakes bake much faster than a normal layered cake.
