On the brighter side in the north, daylight hours will increase every day from now until June

Yes, but we gain very little per day in January, a bit more in February, and in March we really start to notice the difference.

According to the chart above, we do gain daylight a little faster in March and April as opposed to January and February. I theory is that as the year orbits around the sun, the axis changes. This is what causes seasons. But the Earth is not perfectly round, having a sharper radius at the equator.
The table shows we gain about one minute per day and a half in Jan and Feb at sunset and one minute per day at sunset for March an April.
