This year: Sunday, April 21, 2019
In the modern era, every day people are confronted with numbers they need to memorize, whether related to credit card code, password to a computer or other. Such an overflow of information can make it rather difficult for seniors to recall all the important numbers in their lives. Sometimes, this can refer even to birth dates, no matter how privileged one might be.
For example, the British Queen celebrates two dates of birthday: the official one and her real birthday, the day when she was actually born - April, 21. The exact date of the official celebration varies from country to country, and it does not usually mark the real birthday of the sovereign. So, the British Queen has to remember that officially her birthday is now celebrated on the first, second, or third Saturday in June, depending on the country or region. This tradition was introduced in the beginning of the 20th century by Edward VII, who moved the date of the ceremony in hope of good weather, the celebration now being known as the Queen's Official Birthday.
For example, in both Australia and New Zealand Queen's birthday is celebrated on a Monday that falls on different dates every year. The good news for the public is that Queen's birthday comes with a three-day holiday weekend. New Zealand commemorates Queen's birthday on the first Monday of June, while Australia celebrates it on the second Monday of June, except in the Western part where Queen's birthday moves to late September or early October. Probably, the Queen herself has little say in this birth dates "chaos", but it looks like she has what many children would love to have - a birthday almost every month! One might be curious whether the governments of these countries send presents to the Queen on each official date of her birthday celebration. If they do, then it must be great to be the Queen!
April 21 falls under the astrological sign of Taurus. By western astrology, individuals born on April 21 are considered achievers with the qualities of inner poise and an innate ability to project themselves in a way that others cannot, plus the ability to organize and a tendency towards domination.
