Monday’s Child is fair of face,
Tuesday’s child is full of grace,
Wednesday’s child is full of woe,
Thursday’s child has far to go,
Friday’s child is loving and giving,
Saturday’s child works hard for its living
But the child that’s born on the Sabbath day
Is bonny and blithe, and good and gay.
It’s an old rhyme, but one that contains a bit of Astrology.
That idea being that time of birth relates to the nature of the child. To add further interest, consider the origin of the names of the week days.
Monday: named after the Moon
Tuesday: Mars
