How many minutes a day do the day get longer?

Answer 1

-- They only get longer between December 21 and June 21.

For the other half of the year, they get shorter.

-- Just after December 21 and just before June 21, they get longer

very slowly ... only a small difference between one day and the next.

-- Around March 21, they get longer fast ... many minutes' difference

between one day and the next.

EDIT: The length of the day differs by 4 minutes each day throughout the year.
