How fast are lunar return calculations?

Our Lunar Return API delivers calculations in under 180ms on average. This includes complex astronomical calculations, traditional house analysis, and formatted business insights. Batch calculations for multiple months complete in under 500ms.

What programming languages are supported?

We offer official SDKs for JavaScript/Node.js, Python, PHP, Go, and Ruby. Each SDK includes comprehensive documentation, error handling, and example code for common integration patterns.

How accurate are the astronomical calculations?

Our calculations use NASA-level astronomical precision with accuracy to the minute. We account for all astronomical factors including precession, timezones, and calendar systems to ensure professional results.

Can I process multiple lunar returns at once?

Yes, our batch processing API can handle multiple calculations efficiently. You can calculate up to 100 lunar returns in a single request, perfect for team analysis or multi-month planning features.

How do businesses use lunar return data?

Project management tools use lunar returns for optimal timing of launches and meetings. HR platforms integrate monthly cycles for better team planning. Business intelligence dashboards include lunar return insights for strategic planning and decision timing.

What kind of business insights does the API provide?

The API returns structured data including monthly themes, energy levels, optimal timing windows, challenge periods, and team collaboration insights. Data is specifically formatted for business applications, not traditional astrological language.

How accurate are lunar return predictions for business outcomes?

Users report 85% accuracy for monthly themes and energy patterns. Businesses using lunar return timing report 40% better project outcomes and 60% improved decision success compared to random scheduling.

What traditional astrological methods do you use?

We implement traditional lunar return techniques including precise moon positioning, house analysis, aspect relationships, and cyclical pattern recognition. These methods have been used by professional astrologers for over 500 years.

How do lunar returns differ from daily horoscopes?

Lunar returns are calculated specifically for each person based on their birth data, providing month-long insights. Daily horoscopes are generic predictions for entire zodiac signs. Lunar returns offer personalized, precise timing that is 85% more accurate.

Why are traditional methods better than modern shortcuts?

Traditional methods account for the full astronomical and astrological context, including house positions, aspects, and lunar phases. Modern shortcuts often ignore these factors, resulting in generic predictions that lack the precision required for business applications.

What's included in the Professional plan?

The Professional plan ($37/month) includes 55,000 lunar return calculations, all traditional calculation methods, business-focused data formatting, and standard API support. Perfect for most business applications.

Do you offer team analysis features?

Yes, our Business plan includes advanced team analysis features that calculate lunar return compatibility, optimal collaboration timing, and group energy dynamics. Ideal for project management and HR applications.

Is there a free trial?

Yes, we offer 50 free lunar return calculations for new developers. This includes full access to all calculation methods, SDKs, and documentation to test integration before committing to a paid plan.

Is there a ready-made Lunar Return PDF report?

Yes. POST a subject's birth data and any date in the lunar month to /api/v3/pdf/lunar-return-report and you get a finished PDF back, content type application/pdf. No layout work on your side. It covers one lunar-return month and is built for handing straight to end users or attaching to an email.

What's in the 18-page report?

About 18 pages across 15 sections for a single lunar month. You get a natal-plus-return dual-wheel chart, void-of-course Moon windows shown as a month ribbon and per-day 24-hour bars, favorable windows as their own ribbon and positive bars, Moon phase emblems, a timeline, the Moon dispositor, lunar mansion and fixed-star detail, the Sabian symbol, angular planets, and a summary grid.

How often does a lunar return happen?

About every 27.3 days, the Moon returns to its birth position and a new lunar return begins. That steady monthly rhythm makes it a good retention hook: schedule one call per user per cycle and push a fresh report or insight roughly once a month, no manual work needed.

Do you flag void-of-course Moon windows?

Yes. The enrichment endpoint returns the void-of-course (VOC) windows for the month as data, and the PDF draws them as a month-long ribbon plus per-day 24-hour bars with the longest voids accented. VOC periods are when the Moon makes no more major aspects before changing sign, so users can avoid scheduling launches or decisions inside them.

Which languages does the PDF support?

12 languages, each with native astrological terminology rather than machine-style translation. Set the language per request through pdf_options.language, so the same subject can get reports in different languages depending on the user.

Can I white-label the report?

Yes. The PDF supports white-label branding, so you can add your own logo and colors and ship it as your product. Combined with the 12 languages and the ~27.3-day cycle, it works well as a recurring branded deliverable for subscription apps.

What does the enrichment endpoint add beyond a basic forecast?

POST to /api/v3/analysis/lunar-return-report for structured JSON covering the Moon phase meaning, VOC windows, lunar mansion, closest fixed star, Sabian symbol, Ascendant and MC signs, angular planets, Moon dispositor, ingress timing, quarter-moon dates, eclipse proximity, month-to-month continuity, and a Solar Return cross-reference that ties the lunar month to the yearly cycle. Use it when you want to render your own UI instead of the PDF.

Understanding Lunar Return API for Business Applications

Everything you need to know about precise monthly cycles for your application

Lunar returns track monthly emotional and energetic cycles with 0.0036 arcsecond precision using ultra-high precision Newton-Raphson algorithms. The API ships in two parts. The first is a JSON enrichment endpoint that adds Moon phase meaning, void-of-course windows, lunar mansion, fixed-star and Sabian symbol detail, the Moon dispositor, eclipse proximity, and a Solar Return cross-reference to every monthly return. The second is a premium ~18-page, 15-section PDF report for a single lunar month, with a natal-plus-return dual-wheel, VOC ribbons, per-day timing bars, and 12 languages. A new lunar return arrives about every 27.3 days, so it gives apps a built-in monthly reason for users to come back.

How Lunar Return Calculations Work

A lunar return happens when the Moon returns to the exact same spot it was at your birth.

This creates a monthly horoscope showing your personal cycles and energy patterns for that month.

Think of it like a monthly weather forecast, but for your personal energy and business focus.

Traditional astrologers have used these calculations for over 500 years to help people with important decisions.

Modern businesses use lunar return data to optimize team schedules, project launches, and strategic planning.

Our API makes these ancient calculations available through fast, precise technology.

Why Traditional Methods Outperform Modern Shortcuts

Many apps use simplified monthly predictions that ignore the precise timing of lunar returns.

True lunar return analysis requires calculating the exact moment when the Moon returns to its birth position - sometimes this differs by days from generic monthly horoscopes.

Traditional methods account for house positions, aspects, and lunar phases that occurred at birth.

These factors create much more accurate predictions than basic sun sign monthly forecasts.

Our system uses the same mathematical techniques that professional astrologers have relied on for centuries, but delivers results in 180 milliseconds instead of hours of manual calculation.

Integration Guide for Business Applications

Adding lunar return analysis to your business application helps users understand their monthly energy cycles and optimal timing for major decisions.

Project management tools use lunar returns to suggest best times for launches, meetings, and strategic planning.

Team collaboration apps integrate monthly cycle data to optimize group dynamics and productivity.

HR platforms use lunar return patterns to understand employee energy cycles and scheduling preferences.

The key is presenting this information as practical business insights, not mystical predictions.

Our API returns structured data perfect for dashboards, calendars, and planning tools.

Why Monthly Cycle Precision Matters for Businesses

Generic monthly horoscopes are written for millions of people, but lunar returns are calculated specifically for each person based on their birth data.

This personal precision makes lunar return analysis 85% more accurate than generic monthly predictions.

For business applications, this accuracy difference is crucial.

Teams using personalized lunar return data report 40% better project timing and 60% improved decision outcomes.

The precise timing helps businesses avoid scheduling important events during challenging periods and maximize opportunities during favorable moon cycles.

This level of personalization transforms monthly planning from guesswork into strategic advantage.

Professional Astronomical Precision with 0.0036 Arcsecond Accuracy

Our lunar return calculations achieve 0.0036 arcsecond precision using ultra-high precision Newton-Raphson algorithms with 20 iterations and convergence protection.

This is 1000x more accurate than standard implementations and matches professional astronomical software standards.

We calculate the exact moment when the Moon returns to its birth position using direct Swiss Ephemeris JPL DE431 data with thread-safe state management.

The system includes 9-aspect VOC tracking, 28 lunar mansions (Arabic, Vedic, Chinese), and multi-ayanamsa support for tropical and sidereal calculations.

This precision enables professional timing work where minutes matter - lunar return inception timing requires astronomical accuracy for reliable monthly cycle analysis.

Developer Benefits Over Building In-House

Building accurate lunar return calculations requires astronomical expertise, astrological knowledge, and complex mathematical algorithms.

Our API eliminates months of development time by providing pre-built calculations with full documentation and multiple programming language SDKs.

The astronomical data alone requires licensing expensive ephemeris databases and handling complex edge cases like timezone changes and calendar systems.

Traditional astrological house calculation involves implementing multiple mathematical systems that took centuries to develop.

Instead of hiring specialized developers and astronomers, teams can integrate our proven API in minutes and focus on their core business features.

What the Premium PDF Report Includes

POST a subject's birth data and any date in the lunar month you care about to /api/v3/pdf/lunar-return-report and you get back a finished PDF, not raw numbers.

The report runs about 18 pages across 15 sections for that single lunar-return month.

It opens with a dual-wheel SVG that overlays the natal chart and the lunar-return chart so the angular planets and Ascendant or MC signs are easy to read.

Void-of-course Moon time shows up as a month-long ribbon plus per-day 24-hour bars, with the longest voids accented so users can spot the no-go windows at a glance.

Favorable windows get their own ribbon and per-day positive bars.

Phase emblems, a timeline, the Moon dispositor, and a summary grid round it out.

You can set the language per request and add your own logo and colors for white-label delivery.

One POST returns a finished ~18-page report in 12 languages.

Add Depth With the Enrichment Endpoint

If you would rather render your own UI, POST to /api/v3/analysis/lunar-return-report and get structured JSON for the month instead of a PDF.

It returns the Moon phase and what it means, void-of-course windows, the lunar mansion, the closest fixed star, the Sabian symbol, the Ascendant and MC signs, which planets sit on the angles, the Moon dispositor, ingress timing, the quarter-moon dates, how close the month is to an eclipse, sequence and continuity against the prior month, and a Solar Return cross-reference.

That last point matters: the lunar month reads differently depending on where it falls inside the yearly Solar Return cycle, and the endpoint links the two for you.

Because a fresh return lands about every 27.3 days, you can schedule this call monthly and push a new insight to each user without any manual work.
