What's the best time of year to be born, or to give birth?

Do you think there are particularly good times of year to be born or to have a child? Zodiac sign, seasons and weather, foods at certain times of the year, stress levels, school ages based on birthdays, avoiding coinciding with certain holidays, getting to have outdoor birthday parties, .... you name it. I’m curious to hear every answer and the reason(s) for it.

(I Googled and found this” similar question and discussion – but I’m sure there are more ideas about this.)
