Myrtilla Miner (March 4, 1815, near Brookfield, New York – December 17, 1864, Washington, DC) was an American educator and abolitionist whose school for African Americans, established against considerable opposition, grew to a successful and long-lived teachers institution.

Miner was educated at the Clover Street Seminary in Rochester, New York (1840-44), and taught at various schools, including the Newton Female Institute (1846-47) in Whitesville, Mississippi, where she was refused permission to conduct classes for African American girls. In 1851, with encouragement from Henry Ward Beecher and with a board of trustees which included Johns Hopkins and other Quaker philanthropists, Miner opened the Normal School for Colored Girls in Washington, DC. The school was eventually merged with other local institutions to form the University of the District of Columbia.

Shrove Monday, sometimes known as Collop Monday, Rose Monday, Merry Monday or Hall Monday, is the Monday before Ash Wednesday each/every year. A part of the English traditional Shrovetide celebrations of the week before Lent, the Monday precedes Shrove Tuesday. As the Monday before Ash Wednesday, it is part of diverse Carnival celebrations which take place in many parts of the Christian world, from Greece, to Germany, to the Mardi Gras and Carnival of the Americas.

The word shrove is the past tense of the English verb shrive, which means to obtain absolution for one's sins by way of Confession and doing penance. Thus Shrovetide gets its name from the shriving that English Christians were expected to do prior to receiving absolution immediately before Lent begins. Shrove Tuesday is the last day of "shrovetide", somewhat analogous to the Carnival tradition that developed separately in countries of Latin Europe. The term "Shrove Monday" or "Shrove Tuesday" are no longer widely used in the United States outside of Liturgical Traditions, such as the Lutheran, Episcopal, and Roman Catholic Churches.^[1][2]

Green Monday is an online retail industry term similar to Cyber Monday. The term was coined by eBay to describe its best sales day in December^[1], traditionally the 2nd Monday of December. Green Monday is defined more specifically by business research organization comScore as the Monday with at least 10 days prior to Christmas. In 2009, $854 million was spent online in the US on Green Monday,^[2] with sales in 2011 reaching $1.133 billion. ^[3]Green Monday in Greece and Cyprus is the movable feast day known elsewhere in the Greek Orthodox Church as Clean Monday, the first day of Lent - approximately seven weeks before Easter. Traditionally families go to fields to barbecue fasting foods such as vegetables and seafood (not meat), later flying kites and playing other games.

Green Monday also refers to a network of sustainable development practitioners in the UK, which meets on the first Monday of every month in London to discuss critical environmental issues affecting business and industry. Climate change is a major theme.^[4]

The Green March was a strategic mass demonstration in November 1975, coordinated by the Moroccan government, to force Spain to hand over the disputed, autonomous semi-metropolitan Spanish Province of Sahara to Morocco.

Great Lent, or the Great Fast, is the most important fasting season in the church year in Eastern Christianity, which prepares Christians for the greatest feast of the church year, Pascha (Easter). In many ways Great Lent is similar to Lent in Western Christianity. There are some differences in the timing of Lent (besides calculating the date of Easter) and how it is practiced, both liturgically in the public worship of the church and individually.

One difference between Eastern Christianity and Western Christianity is the calculation of the date of Easter (see Computus). Most years, the Eastern Pascha falls after the Western Easter, and it may be as much as five weeks later; occasionally, the two dates coincide. Like Western Lent, Great Lent itself lasts for forty days, but unlike the West, Sundays are included in the count. Great Lent officially begins on Clean Monday, seven weeks before Pascha (Ash Wednesday is not observed in Eastern Christianity) and runs for 40 contiguous days, concluding with the Presanctified Liturgy on Friday of the Sixth Week. The next day is called Lazarus Saturday, the day before Palm Sunday. However, fasting continues throughout the following week, known as Passion Week or Holy Week, and does not end until after the Paschal Vigil early in the morning of Pascha (Easter Sunday).

Clean Monday (Greek: Καθαρά Δευτέρα), also known as Pure Monday, Ash Monday, Monday of Lent or Green Monday, is the first day of the Eastern Orthodox Christian and Eastern Catholic Great Lent. It is a movable feast that occurs at the beginning of the 7th week before Orthodox Easter Sunday.

The common term for this day, "Clean Monday", refers to the leaving behind of sinful attitudes and non-fasting foods. It is sometimes called "Ash Monday," by analogy with Ash Wednesday (the day when the Western Churches begin Lent). The term is often a misnomer, as only a small subset of Eastern Catholic Churches practice the Imposition of Ashes. The Maronite Catholic Church is a notable Eastern rite that employs the use of ashes on this day.

Labour Day or Labor Day is an annual holiday to celebrate the economic and social achievements of workers. Labour Day has its origins in the labour union movement, specifically the eight-hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest.

Celebrating the Australian labour movement, the Labour Day public holiday is fixed by the various state and territory governments, and so varies considerably. It is the first Monday in October in the Australian Capital Territory, New South Wales and South Australia. In both Victoria and Tasmania, it is the second Monday in March (though the latter calls it Eight Hours Day). In Western Australia, Labour Day is the first Monday in March. In both Queensland and the Northern Territory, it is the first Monday in May.
