The first Irish Mathematics Calendar was prepared for 2016. It was the brainchild of Colm Mulcahy as a tangible and useful product of his research on Irish mathematicians. It features many Irish mathematicians from past and present, along with dates of key events of interest to mathematicians. The information highlighted in it was selected by Colm with input from Maurice O'Reilly and others, production was by Eoin Gill and Sheila Donegan and printing and distribution was sponsored by Maths Week Ireland. 1,000 copies were distributed free of charge to mathematicians, teachers and other interested people.
