Saint Valentine's Day or Valentine's Day falls on February 14. It is the traditional day on which lovers express their love for each other; sending Valentine's cards, often anonymously. The holiday is named after two men, both Christian martyrs named Valentine. The day became associated with romantic love in the High Middle Ages, when the tradition of courtly love flourished.

Also known as Washington's Birthday - it is the common name for the United States federal holiday officially designated as Washington's Birthday. It is celebrated on the third Monday of February.

George Washington was actually born on February 11, 1731 of the Julian calendar, in use before England's calendar reformation in September 1752. His birthday is equivalent to February 22, 1732 in the Gregorian calendar used since 1752. Later in life, Washington himself considered the 22d to be his birthday.

Public celebrations for George Washington's birthday actually predate his term as president, in honor of his service during the American Revolutionary War.

In the Western Christian calendar, Ash Wednesday is the first day of Lent and occurs forty days before Easter (excluding Sundays). It falls on a different date each year, because it is dependent on the date of Easter; it can occur as early as February 4 or as late as March 10.

During DST, clocks are turned forward an hour, effectively moving an hour of daylight from the morning to the evening.

Interesting way to remember this: "Spring forward, Fall back"
