There is change in time in different countries because different countries are on different longitudes.
Different countries change their clocks at different times. In some places even within a country. Some countries change the date or day according to local requirements. Then there are countries that do not change their clock time. If you wish to know when a particular country or region makes the alteration then you will need to specify where and what year.
Yes it rains in all countries in Europe one time or another. All the countries have seasons that change.
All the European countries were still Catholic when Henry VII was on the throne, Germany and England would change faiths during Henry VIII's reign.
