How this service works
Dates of round-number days alive (1,000, 5,000, 10,000, 25,000 and your own), with weekday and age on that day.
Output
Returns an array of milestone objects, each with the target day count, the corresponding calendar date (YYYY-MM-DD), weekday name, age in years at that date, days from today (negative if past), and a status label (past/future). Also includes the birth date confirmed, total days alive today, and the reference date used.
Example use cases
Planning a 10,000-day birthday party
“My birthday is July 22, 1987 — when exactly is my 10,000th day alive, and what day of the week does it fall on? I want to plan a party around it.”
Finding a child's milestone days
“My daughter was born on November 5, 2015. Can you list all her major day-alive milestones — 1,000, 5,000, 10,000 days — including the dates, weekdays, and how old she'll be on each one?”
Checking which milestones have already passed
“I was born on January 30, 1975. Which of my round-number day milestones are already in the past and which ones are still coming up? Include how many days ago or from now each one is.”

Endpoint
GEThttps://life-dates.x402tookit.com/milestone-dates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compute the calendar dates of specific round-number day-alive milestones for a person given their birth date. It is ideal for personal milestone celebration planning, age-in-days analytics, or curiosity about life day counts. Prefer it over generic date-difference calculators when you want pre-defined milestone sets with weekday and age annotations in a single call.
Side effects
