3 years dating anniversary gift
The Latin phrase dies natalis (literally "birth day") has become a common term, adopted in many languages, especially in intellectual and institutional circles, for the anniversary of the founding ("legal or statutory birth") of an institution, such as an alma mater (college or other school).Even in ancient Rome, we know of the [dies] Aquilae natalis ("birthday of the eagle", anniversary of the official founding of a legion).
These could be the date of independence of the nation or the adoption of a new constitution or form of government.An anniversary is a day that commemorates or celebrates a past event that occurred on the same date of the year as the initial event.For example, the first event is the initial occurrence or, if planned, the inaugural of the event.One year later would be the first anniversary of that event.The word was first used for Catholic feasts to commemorate saints.The important dates in a sitting monarch's reign may also be commemorated, an event often referred to as a "Jubilee".
Anniversaries of nations are usually marked by the number of years elapsed described with Latin words or Roman numerals.
Latin terms for anniversaries are mostly straightforward, particularly those relating to the first twenty years (1–20), those relating to multiples of ten years (30, 40, 60, 70 etc.), and those relating to multiples of centuries or millennia (100, 200, 300, 1000, 2000, 3000 etc.) In these instances, the anniversary generally comes from a derivative of the Latin word for the respective number of years. There were also special terms for quarter (quadrans), half (semis), and three-quarters (dodrans).
However, when anniversaries relate to fractions of centuries (125, 150, 175, 250 years—i.e., 1.25, 1.5, 1.75, and 2.5 centuries), the situation is not as simple. Dodrans is a Latin contraction of de-quadrans which means "a whole unit less a quarter" (de means "from"; quadrans means "quarter".
Thus for the example of 175 years, the term is a quarter century less than the next whole (bi)century or 175 = (-25 + 200).
In Latin it seems that this rule did not apply literally for 1½.
Whereas "secundus" is Latin for "second", or "bis" for "twice" these terms are not used such as in sesqui-secundus. This may be because it relates to a ratio of one—thus it means "and a half" compared to "one".
