I have to be awkward and want my character or character's wife to have girl child on 1st Spring... Mainly so I can call her Sakura.

Could anyone please tell me the date I would need characters to propose or marry on for...
Rune Factory Frontier
Rune Factory 2
2nd child on Harvest Moon Animal Parade
any of the other Harvest Moon games
for a girl to be born on first of Spring if possible. Thankyou.

If anyone else has something they have to have in a HM or RF game please share.
