Thursday marks the spring equinox, when the duration of darkness and daylight are roughly about the same everywhere on Earth —about 12 hours each.
In Finland, statistics indicate that there is a higher probability of catching a glimpse of the northern lights (or aurora borealis) around this time of the year.
Daylight hours will continue to grow until the summer solstice, after which the amount of daylight starts shrinking again. This year the summer solstice falls on 21 June, the same day as the Midsummer holiday.
In Finland daylight hours will continue to increase by about five to 10 minutes per day until then.
Last year, the All Points North podcast chased the northern lights in Finnish Lapland. Listen to the episode via this embedded player, on Yle Areena via Apple or Spotify or wherever you get your podcasts.
