How many minutes of daylight do you gain each day in Jan?

Answer 1

Depends on your latitude, but daylight gain is at a minimum after the winter solstice dwell point ( northern hemisphere) up to maximum daily gain at the spring equinox, gain per day then falls to 0 at the summer solstice dwell point, then this trend is reversed down to the winter solstice, completing the cycle.

The graph of daylight hours in say england, resembles a sine curve.
