This year's calendar displays artwork from past calendar winners in a colourful compilation.
As in previous years there is the 2021 calendar year on one side and the 2021-22 financial year on the other side for people to plan ahead.
Dr John Byrne said he would like to thank all the previous winners who contributed to making the 2021 calendar so vibrant.
"We have been so lucky to receive so many wonderful works of art for our calendar competitions over the years.
"I felt very happy this year that I didn't have to choose a winner this year, as it is always such a difficult task," he said.
Hardcopies of the calendar will be mailed out later in the month if you like a calendar please fill out the publications order form on our Fact Sheets and other resources page.
