# Lunara Astro > Lunara (https://lunaraastro.com) is an astrology website with free calculators and optional paid reports. Positions are calculated with the Swiss Ephemeris (tropical zodiac; Placidus houses when a birth time is known). Free tools return calculated placements; paid reports are separate, optional, written interpretations of a chart. ## Free calculators - Natal (birth) chart: https://lunaraastro.com/free-natal-chart-calculator — Sun, Moon, planets; Rising sign and houses only when a birth time is entered. - Moon sign without a birth time: https://lunaraastro.com/moon-sign-without-birth-time — shows whether the Moon stayed in one sign on that local date or changed sign, and roughly when. - Venus return: https://lunaraastro.com/venus-return - Saturn return: https://lunaraastro.com/saturn-return-calculator - Planets retrograde at birth: https://lunaraastro.com/retrograde-planets-calculator - Black Moon Lilith sign (mean lunar apogee): https://lunaraastro.com/lilith-sign-calculator - Stellium (three or more planets in one sign): https://lunaraastro.com/stellium-calculator - Chart ruler: https://lunaraastro.com/chart-ruler-calculator — look up the traditional ruler (and the modern co-ruler for Scorpio, Aquarius and Pisces) from a known rising sign. The ruler's natal sign and Placidus house need an exact birth time and place. - North Node and South Node: https://lunaraastro.com/north-node-calculator — the true lunar node and the opposite South Node. Birth time is optional; without it the whole local birth day is sampled, and both sign candidates are shown when the node is near a sign boundary. - Midheaven (MC) and IC: https://lunaraastro.com/midheaven-calculator — from a known birth time and place; the time is required and the result depends on location. - Jupiter return: https://lunaraastro.com/jupiter-return-calculator — date of birth only. Estimates the current or next Jupiter return episode using a 12:00 UTC natal reference, and can list repeated passes. It is not a paid return forecast. - Synastry / relationship chart for two people: https://lunaraastro.com/synastry-chart - Free Moon widget for websites: https://lunaraastro.com/free-moon-widget — a copy-and-paste image badge showing the current tropical geocentric Moon sign and phase (cached about 10 minutes); free with visible attribution. - Chart night host kit: https://lunaraastro.com/chart-night — a free 20-minute agenda, ground rules, invitation text and a printable sheet for friends who each make their own chart privately; nobody has to share birth details. - Directory of all free calculators: https://lunaraastro.com/tools - Celebrity natal charts with the source of each birth record: https://lunaraastro.com/celebrities ## Editorial - Blog: https://lunaraastro.com/blog — original editorial in English. Celebrity articles use public birth data with the clock limits stated; where no reliable birth time exists, the chart is date-only. ## Optional paid reports and samples Paid reports are offered after a free chart is calculated: a personal natal reading and a two-person synastry reading. Full samples built from fictional birth data, so readers can see the format before paying: - Natal reading sample: https://lunaraastro.com/natal-reading-sample - Synastry reading sample: https://lunaraastro.com/reading-sample - About the personal natal reading: https://lunaraastro.com/personal-birth-chart-reading ## Transit and event guides - Mercury retrograde in Scorpio 2026: https://lunaraastro.com/mercury-retrograde-scorpio-2026 - Venus retrograde 2026: https://lunaraastro.com/venus-retrograde-2026 - Saturn in Aries 2026: https://lunaraastro.com/saturn-in-aries-2026 - Jupiter in Leo 2026: https://lunaraastro.com/jupiter-in-leo-2026 - Solar eclipse, August 2027: https://lunaraastro.com/solar-eclipse-august-2027 - 2027 astrology calendar (New and Full Moons, Sun sign ingresses, Mercury stations; UTC, with .ics and JSON): https://lunaraastro.com/astrology-calendar-2027 ## Languages The site is available in 10 locales: English (default, no prefix), Spanish (/es), Arabic (/ar), French (/fr), German (/de), Russian (/ru), Turkish (/tr), Chinese (/zh), Italian (/it) and Portuguese (/pt). Not every page exists in every locale, and non-English URLs of English-only pages redirect to the English page. The natal chart, synastry, Saturn return and Venus return pages and the samples have localized pages; how much of each page is translated varies by locale. The retrograde planets and Lilith calculators and the Jupiter in Leo guide are English and Spanish only. The Mercury, Venus, Saturn and eclipse guides are English, Spanish and Arabic. The Moon-without-birth-time, stellium, chart ruler, North Node, Midheaven and Jupiter return calculators and the blog are English only. ## MCP server (for AI apps) - Endpoint: https://lunaraastro.com/api/mcp (JSON-RPC over HTTP POST) - One tool only: `generate_natal_chart` (inputs: `birthDate` YYYY-MM-DD, `location` as a place name or {name, lat, lon}, optional `birthTime` HH:MM local time). - It returns calculated chart text. It does not return a chart-wheel image or a paid reading. - If `birthTime` is omitted, the time is treated as unknown, not guessed: Rising sign, Midheaven and houses are withheld, and planets are shown as values for 12:00 local time on that date, for reference only. The Moon's degree (and on some dates its sign) depends on the missing time. - Other tasks (Moon without a birth time, returns, retrogrades, Lilith, stellium, synastry) are handled by the web pages above, not by the MCP tool. ## Limits Calculated positions depend on the birth data entered; an unknown or approximate birth time makes the Rising sign, houses and Moon degree uncertain. Interpretive text on the site and in reports is written with AI assistance and assembled from the calculated placements. It is not a personal consultation with an astrologer. Astrology is for reflection and entertainment, not medical, legal, financial or psychological advice.
