In the past, schools have taken a half-day holiday, which continues in some parts of Wales. Saint David's Day is also celebrated in expatriate Welsh communities outside the UK. Cross-party support resulted in the National Assembly for Wales voting unanimously to make Saint David's Day a public holiday in 2000. A poll conducted for Saint David's Day in 2006 found that 87% of people in Wales wanted it to be a bank holiday, with 65% prepared to sacrifice a different bank holiday to achieve this. A petition in 2007 to make Saint David's Day a bank holiday was rejected by the office of the British Prime Minister Tony Blair.

It can exist either in an anhydrous (water-free) form or as a monohydrate. The anhydrous form crystallizes from hot water, while the monohydrate forms when citric acid is crystallized from cold water. The monohydrate can be converted to the anhydrous form at about 78 °C. Citric acid also dissolves in absolute (anhydrous) ethanol (76 parts of citric acid per 100 parts of ethanol) at 15 °C. It decomposes with loss of carbon dioxide above about 175 °C.

The term superfecundation is derived from fecund, meaning the ability to produce offspring. Heteropaternal superfecundation refers to the fertilization of two separate ova by two different fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins. While heteropaternal superfecundation is referred to as a form of atypical twinning, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either separate occurrences of sexual intercourse or through artificial insemination.
