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.

Should say: My theory is that as the earth orbits around the sun, the axis changes.

I don't know much, but the Earth's orbit is ellipical, not round. That could be the cause (though the deviation from the circular is actually small.)
