Free Nordic planning tool
Calculate approximate sunrise, sunset and daylight for Nordic capitals and Arctic bases including Tromsø, Lofoten, Kiruna, Abisko, Rovaniemi and Ivalo.
Your scenario
Nothing is prefilled. Use figures from the job offer, home, institution, route or trip you are actually considering.
Question this tool answers
How much astronomical daylight should you expect at a Nordic city or Arctic base on a chosen date?
Daylight planning
Choose a Nordic city or Arctic base and a date. Times are calculated astronomically and formatted in the destination time zone.
Your result
Choose a destination and date to see the daylight window.
Calculated sunrise/sunset is an approximation based on standard solar equations and atmospheric refraction assumptions. Mountains, local horizon, weather and atmospheric conditions change the observed moment. Use this for itinerary planning, not navigation or safety-critical decisions.
Inputs that matter
What it does not prove
Sunrise and sunset are calculated approximations. Mountains, local horizon, atmospheric conditions and twilight change the light you actually experience.
Best next step
Use the result as a filter, then verify the decision in the detailed guide and current source.
Use daylight in the Nordic travel plan →After you calculate
01
Compare two candidate dates before choosing flights.
02
Use daylight together with weather and activity access, not as a stand-alone best-month score.
03
For aurora travel, remember that darkness is necessary but does not guarantee clear sky or aurora activity.
FAQ
Example values can make a planning tool look more precise than it is. The fields start empty so the result is based on your own offer, rent, household, route or travel assumptions. Placeholders show the expected format only and are not used in the calculation.
Sunrise and sunset are calculated approximations. Mountains, local horizon, atmospheric conditions and twilight change the light you actually experience. Use the result to compare scenarios, then verify the relevant current source or detailed guide before making a financial, immigration, study, housing or travel commitment.
