Question: In the early morning of 10 April, leading elements of the Austrian army crossed the Inn River and invaded Bavaria. The early Austrian attack surprised the French; Napoleon himself was still in Paris when he heard about the invasion. He arrived at Donauworth on the 17th to find the Grande Armee in a dangerous position, with its two wings separated by 75 miles (121 km) and joined together by a thin cordon of Bavarian troops. Charles pressed the left wing of the French army and hurled his men towards the III Corps of Marshal Davout. In response, Napoleon came up with a plan to cut off the Austrians in the celebrated Landshut Maneuver. He realigned the axis of his army and marched his soldiers towards the town of Eckmuhl. The French scored a convincing win in the resulting Battle of Eckmuhl, forcing Charles to withdraw his forces over the Danube and into Bohemia. On 13 May, Vienna fell for the second time in four years, although the war continued since most of the Austrian army had survived the initial engagements in Southern Germany.
Is there an answer to this question: On what date did the Austrian army first cross the Inn River?

Answer: 10 April

Question: Palermo experiences a hot-summer Mediterranean climate (Koppen climate classification: Csa). Winters are cool and wet, while summers are hot and dry. Temperatures in autumn and spring are usually mild. Palermo is one of the warmest cities in Europe (mainly due to its warm nights), with an average annual air temperature of 18.5 C (65.3 F). It receives approximately 2,530 hours of sunshine per year. Snow is usually a rare occurrence, but it does occur occasionally if there is a cold front, as the Apennines are too distant to protect the island from cold winds blowing from the Balkans, and the mountains surrounding the city facilite the formation of snow accumulation in Palermo, especially at night. Between the 1940s and the 2000s there have been eleven times when considerable snowfall has occurred: In 1949, in 1956, when the minimum temperature went down to 0 C (32 F) and the city was blanketed by several centimeters of snow. Snow also occurred in 1999, 2009 and 2015. The average annual temperature of the sea is above 19 C (66 F); from 14 C (57 F) in February to 26 C (79 F) in August. In the period from May to November, the average sea temperature exceeds 18 C (64 F) and in the period from June to October, the average sea temperature exceeds 21 C (70 F).
