What was the moon phase on my birthday, July 14, 1998? I was born in Chicago.
Description
From the marketplace listing
See the real Moon and the real night sky for the dates that matter: a birthday, a wedding, the night you met. Moon & Star Map computes the Moon phase for any date from 1800 to 2200 with astronomical algorithms (Jean Meeus): the phase name, the exact illumination percentage, the moon age in days, whether it was waxing or waning, the exact times of the new, quarter and full moons, and the next full and new moon. Give two birthdays and it tells you whether your moons "complete each other" (half a lunar cycle apart, so one moon's light fills the other's shadow), with a match score and an honest explanation. Ask for a month and you get a moon phase calendar with every day drawn. For a star map, name a city, a date and a local time. Time zones and daylight saving time are handled for you, and the city match is stated in the reply. The map shows about 2,900 stars from the Yale Bright Star Catalog sized by brightness, the constellation lines, the horizon, the cardinal points and the Moon in its real position and phase. You see a live preview, can switch between four styles (midnight, black, paper, ink) and toggle lines and labels, then download vector poster PDFs at 12x18 in, 18x24 in, A3, US Letter and A4 (with 0.125 in print bleed), an SVG, and a share page anyone can open. Moon posters: one date's moon as a large print, two dates side by side for couples, or a lunar calendar of a whole year. Good for anniversary, wedding, birthday and new-baby keepsakes, classroom moon charts, and answering "what was the moon on the day I was born?". Accuracy: moon illumination matches an independent ephemeris within 0.5 percentage points and phase times within about a minute for 1900-2100; star positions match within 0.1 degree. Limitations: decorative keepsakes, not for navigation or telescope pointing. Planets, the Milky Way and eclipses are not drawn. Cities come from a list of about 11,000 places; give a nearby larger city if yours is missing. PDF text covers Latin, Greek and Cyrillic letters; Chinese, Japanese and Korean titles appear in the SVG only. Data: GeoNames (CC BY 4.0), Yale Bright Star Catalog, constellation lines from d3-celestial by Olaf Frohn (BSD-3-Clause), astronomia (MIT).

# Moon & Star Map
Pick the tool from the request:
- **find_moon_phase**: "what was the moon on my birthday", "moon phase tonight", "do our moons complete each other / make a full moon", "moon calendar for July". Pass `dates` as `YYYY-MM-DD` (add `THH:MM` if the user gives a time), `labels` for names, `month` as `YYYY-MM` for a calendar, and `city` when the user names a place (it sets the time zone and hemisphere). With no dates and no month it answers for right now.
- **generate_star_map**: a star map or night-sky poster for a date and place. Needs `city` and `date`; pass `time` (local HH:MM) when given, otherwise 21:00 is used and the reply says so. Optional `title`, `message`, `theme` (midnight, black, paper, ink), `constellations`, `labels`, `show_moon`.
- **generate_moon_poster**: a printable moon print: `kind=moon` (one date), `kind=pair` (two dates, e.g. a couple), `kind=year` (lunar calendar of `year`).
Rules:
1. Never ask for or pass latitude/longitude. Use the city name, adding a state or country when it is ambiguous ("Paris, Texas", "Portland, Maine"). Say which city was matched.
2. Convert spoken dates to `YYYY-MM-DD` yourself ("July 14, 1998" -> `1998-07-14`). Ask only if the year is missing.
3. Report the numbers from the tool as given (phase, illumination %, moon age, exact phase times with the time zone). For two dates, relay the verdict and the honest explanation; it is a playful idea, not astrology.
4. Share the PDF/SVG download links and the share page link for posters. Mention that posters are decorative keepsakes, not for navigation.
Do not use this skill for horoscopes or astrology readings, eclipse predictions, planet positions, tides, moonrise times, or telescope pointing.
