Civic Holiday is the most widely used name for a public holiday celebrated in parts of Canada on the first Monday in August,^[1] though it is only officially known by that term in Nunavut, the Northwest Territories, Prince Edward Island, and Manitoba. It is a statutory holiday in Nunavut, the Northwest Territories, and Prince Edward Island, but not in Manitoba.

The date of the Civic Holiday is historically linked to the abolition of slavery in the British Empire in 1834,^{[citation needed]} but was chosen primarily for its timing: between Canada Day and Labour Day there were no recognizable holidays, one of the longest stretches on the Canadian calendar without a holiday. (In terms of statutory holidays, the winter stretch between Family Day and Easter is occasionally longer, but unofficial holidays such as Saint Patrick's Day and Valentine's Day are observed during that time.) Thus, this holiday was placed roughly halfway between Canada Day and Labour Day; it is celebrated under numerous names in the jurisdictions it is recognized. In many communities, however, Emancipation Day celebrations are also held, specifically commemorating the abolition of slavery in Canada in 1834.

(Arabic: عيد وفاء النيل‎) has been an important natal cycle in Egypt since ancient times. It is celebrated by Egyptians as an annual holiday for two weeks starting August 15, known as Wafaa El-Nil. It is also celebrated in the Coptic Church by ceremonially throwing a martyr's relic into the river, hence the name, Esba` al-shahīd ('The Martyr's Finger'). Ancient Egyptians believed that the Nile flooded every year because of Isis's tears of sorrow for her dead husband, Osiris.

The three stages of the Egyptian flood cycle were Akhet, the time of the Nile flood, Peret, the sowing time, and Shemu, the time of harvest. Without this cycle people would die from starvation.The flood cycle was so predictable that the Egyptians even based their ancient calendar on it. Akhet was the first season of the year, between the months of June and September. Peret or the Egyptian Autumn season marked the time when their crops grew in the fields and were harvested,^[1] running from October to mid-February. Shemu was the third and last season of the Egyptian year which ran from mid-February until the end of May; it essentially signalled the spring season of the Egyptian calendar.^[2]
