Encyclopedia of birth symbols

BirthDB currently returns one representative birthstone label for each month.

This mapping comes from BirthDB's shared month table and does not switch to a different table by country or language.

For entertainment, treat the stone name as an invitation to learn about the gem rather than as advice or a promised effect.

BirthDB calculates the weekday from the full Gregorian date in UTC.

A month and day without a year is not enough to produce a weekday.

For entertainment, use the weekday as a prompt to look for other dated events in the timeline.

BirthDB reads birth flower, birth tree, birth cocktail, guardian planet, guardian figure, and zodiac-week labels from its approved date-range tables.

A month-day can match only one stored range on each axis, and the same rule handles a range that crosses the end of the year.

These labels are editorial browsing categories, not evidence of an effect or a person's traits.
