What this server can do

4 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

get_baby_age(birthday)
Get a baby's exact age from a birth date - years, months, weeks, days, totals, zodiac sign, the current and next milestone, and special-day dates (100 days, first birthday, 1000 days). Use for any 'how old is the baby' question instead of computing it yourself. Required: birthday.
get_milestone_dates(birthday)
Get the exact calendar date of all 25 baby milestones for a given birth date (monthly, special days, and birthdays), each with days_left and whether it is reached. Use this to add baby milestones to a calendar. Required: birthday.
get_zodiac_sign(birthday)
Get the zodiac sign (Western astrology) for a birth date, with element, nickname, date range, and a guide link. Required: birthday.
list_milestones
List the 25 baby milestone types this tool knows (name, emoji, day offset from birth, group). No birth date needed. Use get_milestone_dates to turn these into real dates.
