While the mean speed of the Earth on its solar orbit is about 30km/sec, what is its approximate speed during the both equinoxes and the both solstices ?

Thank you. But the difference is so small ? Then I do not understand why the day increase is so different at 23 December and at 23 March, for instance.

Yes, thank you I have understood already why day in/de-crease slowly at solstices and do so more rapidly at equinoxes - angular speeds at perihelion/ aphelion vs the other parts of the orbit (do not know the right term) are different, not speed of Earth as I imagined.
