Personal day in numerology

Personal day: how the API works it out
The API starts from the personal month number for the as_of date and adds the day of the month. Then it reduces the sum. To reduce means to add the digits until one digit is left.
The result is always 1 to 9. For John Doe, born August 15, 1990, the personal month for October 2026 is 7. On October 1, that gives 7 plus 1, so his personal day is 8.
The reading for 8 says the day is good for work, money and big decisions. POST /v1/cycles returns it under day, with number, an about line and a reading. The route needs only the birth date, and one live call costs 2 reading credits.
Send as_of for a given date, or leave it out to use today. POST /v1/dates returns personal_day for every date of a month, beside each date's own number. There the personal day is a theme only, and it is not judged good or bad.
The outcome on each date comes from the date's own number. That number is read against the mulank (birth day number) and the bhagyank (destiny number). GET /v1/day is a different thing again.
It gives the number of the date itself, which is the same for everyone and needs no birth date.
