National Programmers Day
The Day of the Programmer is an international professional day recognized in many technology companies and programming firms, that is celebrated on the 256th (hexadecimal 100th, or the 28th) day of each year (September 13 during common years and on September 12 in leap years). The number 256 was chosen because it is the number of distinct values that can be represented with an eight-bit byte.
In 1970, a West Virginia housewife, Marian McQuade, initiated a campaign to set aside a special day just for Grandparents. In 1978, the United States Congress passed legislation proclaiming the first Sunday after Labor Day as National Grandparents Day. The proclamation was signed by President Jimmy Carter.
