Here is a question about this article: The Gregorian calendar improves the approximation made by the Julian calendar by skipping three Julian leap days in every 400 years, giving an average year of 365.2425 mean solar days long. This approximation has an error of about one day per 3,300 years with respect to the mean tropical year. However, because of the precession of the equinoxes, the error with respect to the vernal equinox (which occurs, on average, 365.24237 days apart near 2000) is 1 day every 7,700 years, assuming a constant time interval between vernal equinoxes, which is not true. By any criterion, the Gregorian calendar is substantially more accurate than the 1 day in 128 years error of the Julian calendar (average year 365.25 days).
What is the answer to this question: How many days must be skipped to align the calendar with mean solar days in a year?
****
So... three Julian leap days


Here is a question about this article: The year 1789 brought the French Revolution and with it the first division of Alsace into the départements of Haut- and Bas-Rhin. Alsatians played an active role in the French Revolution. On 21 July 1789, after receiving news of the Storming of the Bastille in Paris, a crowd of people stormed the Strasbourg city hall, forcing the city administrators to flee and putting symbolically an end to the feudal system in Alsace. In 1792, Rouget de Lisle composed in Strasbourg the Revolutionary marching song "La Marseillaise" (as Marching song for the Army of the Rhine), which later became the anthem of France. "La Marseillaise" was played for the first time in April of that year in front of the mayor of Strasbourg Philippe-Frédéric de Dietrich. Some of the most famous generals of the French Revolution also came from Alsace, notably Kellermann, the victor of Valmy, Kléber, who led the armies of the French Republic in Vendée and Westermann, who also fought in the Vendée.
What is the answer to this question: In what year did the division of Alsace take place?
****
So... 1789


Here is a question about this article: Many of the coinages that have been considered (often by Aavik himself) as words concocted ex nihilo could well have been influenced by foreign lexical items, for example words from Russian, German, French, Finnish, English and Swedish. Aavik had a broad classical education and knew Ancient Greek, Latin and French. Consider roim ‘crime’ versus English crime or taunima ‘to condemn, disapprove’ versus Finnish tuomita ‘to condemn, to judge’ (these Aavikisms appear in Aavik’s 1921 dictionary). These words might be better regarded as a peculiar manifestation of morpho-phonemic adaptation of a foreign lexical item.
What is the answer to this question: What is another term for words created by Aavik?

So...
Aavikisms
