Easter comes near to the time of the spring equinox on 21 March, when the length of the day and night are equal
The date of Easter is not fixed, but always falls on the first Sunday following the full moon that occurs on or after the spring equinox, making it any time between March 22 and April 25.
Decorating and colouring Easter eggs was a popular custom in the middle ages, and throughout Europe different cultures have evolved their own styles and colours. In Greece, crimson-coloured Easter eggs are exchanged, whereas in Eastern Europe and Russia silver and gold decorations are common, and Austrian Easter eggs often have plant and fern designs. Easter eggs have been coloured and decorated from earliest times. Later, craftsmen made artificial eggs of silver and gold, ivory or porcelain, often inlaid with jewels. The ultimate Easter egg-shaped gifts must have been the fabulous jewelled creations by Carl Fabergé made during the 19th Century for the Russian Czar and Czarina. Today, these superb creations are precious museum pieces.
In the 18th century, people could buy pasteboard or papier-maché eggs, in which they hid small gifts. By the 19th century cardboard eggs covered with silk, lace or velvet and fastened with ribbon were fashionable.
The chocolate Easter egg has developed from the simple type wrapped in paper to the beribboned variety wrapped in brightest foil and packed in a box or basket. The first chocolate Easter eggs were made in Europe in the early 19th Century with France and Germany taking the lead in this new artistic confectionery.
