Depends where, as well as the individual person. Generally, wealthy Western Europeans spent time in cities in the fall and winter, when they would manage their estates, attend social events like the theater and music concerts, as well as commission artwork and do indoors-y things; while they would spent time in the country in the summer, riding on horseback, reading, writing letters, and doing generally outdoors-y things.

I wrote about "Town and Country" rituals in the Republic of Venice in this earlier answer. Feel free to ask any additional questions!
