13 September-Programmers’ Day

Programmers’ Day, also referred to as The Day of the Programmer, is celebrated on the 256th day of each year. The day celebrates the work of computer programmers and the effect their work has on our everyday lives. It was proposed by Valentin Balt and Michael Cherviakov and a decree recognising the day was signed by Russian President, Dmitry Medvedev in 2009.

The 256th day of the year was chosen as Programmers’ Day because this is the number of distinct values that can be represented with an eight-bit byte. It is also the highest power of two which is less than 365.

Programmers’ Day is celebrated every year (except Leap Years, when it is celebrated the previous day), On This Day.

23 June-Bonfire Night

Bonfires are lit in many parts of Ireland on June 23rd to celebrate St John’s Eve. Though it was once widely celebrated throughout the country, it takes place nowadays mostly in the west. Fires are lit around sunset and the evening is a festive occasion for the local community. It is believed to be an ancient pre Christian custom which celebrated the Summer Solstice.
