Costa Rica is basically Mountain Daylight time, 2 zones behind Eastern Daylight time. But Costa Rica doesn't make the Daylight to Standard time change, so that after (most of the) US switches to Standard time on November 3 CR will only be 1 hour behind East Coast.
Last year we had a series of posts watching sunset time in Poland. We can do that again for Costa Rica, but it's gonna get pretty boring because there won't be much variance. The reason, latitude. Latitude is a measurement that locates a point on a planet in relation to its distance from the equator. Higher latitudes are closer to the poles, while 0 latitude is the equator itself.
At the equator, there are 12 hours of sunlight and 12 hours of darkness - the day is split in half. Because the distance from the sun never changes.
Poland is basically latitude 50-55. So, in the winter Poland is tilted away from the sun and the rays of the sun reach it for much fewer hours -- while in the summer Poland is pointed toward the sun and gets many more hours of sun. Same as in Charlotte (to a lesser extent). Same as in Boston, Chicago, Toronto.
Costa Rica is latitude 9-10, and greater than the equator at 0, there's not gonna be much change in the distance from the sun, not much change in the degrees of tilt away, not much change in the hours of sunlight. We'll watch this over the next four months.
