Holidays and observances

April 25 is recognized for several national and international observances:

• ANZAC Day: A national day of remembrance in Australia, New Zealand, and Tonga that broadly commemorates all Australians and New Zealanders who served and died in all wars, conflicts, and peacekeeping operations.

• DNA Day: An annual holiday celebrated to commemorate the day in 1953 when James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin, and colleagues published papers in the journal Nature detailing the double helix structure of DNA. It also marks the completion of the Human Genome Project in 2003.
