Compare daylight
Pick two cities to see how their days line up, today and through the year.
In 2026, Oslo ranges from 5h 54m to 18h 50m of daylight; Buenos Aires from 9h 50m to 14h 29m. Their seasons are opposite: Oslo’s longest day comes in June, Buenos Aires’s in December.
Day length is sunset minus sunrise in each city’s own time zone. 2026 dates.
