How many minutes of daylight do we gain or lose each day?

In August, the rate has now sped up to about 2 minutes per day. Over the next month, we will lose an additional 1 hour and 8 minutes. We continue to lose daylight until the winter solstice on December 21, when sunrise is 7:36 a.m., and sunset is 5:21p.m. Shorter days translate to cooler weather.

In this regard, how many hours are actually in a day?

You're right that a "sidereal" day is about 23 hours, 56 minutes, 4 seconds. But this is not a day in the everyday sense. A sidereal day is how long it takes the earth (on average) to make one rotation relative to the faraway stars and other galaxies in the sky.

Is there more than 24 hours in a day?

This period of rotation is about 4 minutes less than 24 hours (23 hours 56 minutes and 4.1 seconds) and there are about 366.242 2 stellar days in one mean tropical year (one stellar day more than the number of solar days).

How many minutes per day is it getting lighter?

Following December 21, as the sunrise slowly arrives later over those 17 days, we add, at best, a mere minute of daylight to each day at sunset. By January 7, though, we're adding a full two minutes each day to the daylight hours --one at sunrise and one at sunset.
