Saint Patrick (c. 385 – c. 461), the foremost patron saint of Ireland. Saint Patrick's Day, or the Feast of Saint Patrick, commemorates Saint Patrick and the arrival of Christianity in Ireland, and, by extension, celebrates the heritage and culture of the Irish in general. Initially, it was a religious observance, but it evolved into a secular celebration of Irish culture and heritage, particularly due to the Irish diaspora. It is now celebrated annually on March 17, in more than 200 countries. More

Groundhog Day, is a popular North American tradition observed in the United States and Canada on February 2. The weather lore was brought from German-speaking areas where the badger (German: Dachs) is the forecasting animal. This appears to be an enhanced version of the lore that clear weather on the Christian festival of Candlemas forebodes a prolonged winter. As the tradition goes, if a groundhog emerges from its burrows on this day and sees its shadow due to clear weather, it will retreat to its den and winter will go on for six more weeks; if it does not see its shadow because of cloudiness, spring will arrive early. While the tradition remains popular, studies have found no consistent association between a groundhog seeing its shadow and the subsequent arrival time of spring-like weather. In the U.S , the most popular Groundhog ceremony is held at Punxsutawney in western Pennsylvania, centering on a semi-mythical groundhog named Punxsutawney Phil. Other cities in the United States and Canada also have adopted the event. More

There are only two moments each year when the Sun lies directly above Earth’s equator. These moments are the equinoxes, when, at any location, the lengths of day and night are roughly equal. The March equinox happens sometime between March 19 and 21. The September equinox occurs sometime between September 21 and 24.
In the Northern Hemisphere, the March equinox marks the beginning of Spring and the September equinox the beginning of Fall. The reverse takes place in the Southern Hemisphere.
