In chronobiology, the circannual cycle is characterized by biological processes and behaviors recurring on an approximate annual basis, spanning a period of about one year. This term is particularly relevant in the analysis of seasonal environmental changes and their influence on the physiology, behavior, and life cycles of organisms.
The observance of Groundhog Day in the United States first occurred in German communities in Pennsylvania, according to known records. The earliest mention of Groundhog Day is an entry on February 2, 1840, in the diary of James L. Morris of Morgantown, in Pennsylvania Dutch Country, according to the book on the subject by Don Yoder.

In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
The alpine marmot (Marmota marmota) is a large ground-dwelling squirrel, from the genus of marmots.It is found in high numbers in mountainous areas of central and southern Europe, [2] at heights between 800 and 3,200 m (2,600–10,500 ft) in the Alps, Carpathians, Tatras and Northern Apennines.
BGS Groundhog Desktop is a software tool developed and made available by the British Geological Survey and used for geological data visualisation, interpretation and 3D geologic modelling. It is available in both free-to-use and commercial editions. Groundhog Desktop is a key part of the BGS's work to develop 3D models of the UK subsurface. [1]
The major plot device is a time loop or time bounce, and bears great similarity to that of 1993's Groundhog Day. Lupoff and Jonathan Heap, director of the 1990 film, were "outraged" by the apparent theft of the idea, but after six months of lawyers' conferences, they decided to drop the case against Columbia Pictures.
