Daylight increase is not a linear function.
It is very low at each solstice and equinox, slowly increases to mid term and then decreases again.
Latitude also needs to be taken into account.
Days never get shorter, they are always the same length. We do, however, lose a few minutes of daylight each day from June 21 to December 21. It's hard to say exactly how many minutes because it depends on one's latitude. Somewhere around 3-4 minutes for those of us in the continental US, I'd guess.
