Solunis means Solar Lunar Intelligence System: one cross-platform app for many calendar systems, observances, precise astronomical timing, and reminders.
Solunis brings calendars, observances, festival discovery, and reminder automation together in one product.
Tithi, Vara, Nakshatra, Yoga, and Karana computed in real-time. Identify auspicious windows for ceremonies, decisions, and events.
Detect religious festivals, national holidays, and regional observances for every faith and country — automatically.
Create reminder schedules for observances, ceremonies, travel, and personal planning with timezone-aware delivery across devices.
Government-grade holiday datasets for 190+ countries, with regional and state-level granularity for enterprise and institutional use.
Earth Day, World Water Day, biodiversity observances, and UN-designated environmental days tracked and surfaced intelligently.
Live conversion between Gregorian, Hijri, Hebrew, Chinese, Buddhist, Nepali, Vikram Samvat, Malayalam, Tamil, Jain, and many more — simultaneously.
Sub-arcsecond solar and lunar longitude computation. Transition timing accurate to the second for any global location.
Explore where Solunis is launching next. Desktop, mobile, and web access are all part of the same roadmap, with release work currently in progress for each platform.
Solunis supports a much broader set of sacred, regional, and civil calendar systems, with real-time synchronization, correct epoch computation, and intercalation handling for each tradition.
From personal planning to institutional observance management, Solunis serves people and teams that depend on correct calendar context and trustworthy timing.
Precise Panchanga, Muhurta, and festival timing for daily puja and ceremony scheduling.
Portable, reliable timing on any device, including offline use for remote communities.
Find auspicious dates, follow observances, and manage reminders for weddings, travel, family events, and daily decisions.
Multi-faith calendar management for mosques, synagogues, temples, churches, and monasteries.
Holiday, observance, and reminder intelligence for HR systems, scheduling platforms, and global teams.
Official national and regional holiday computation for civic systems and public services.
REST API infrastructure for calendar apps, faith-tech products, and institutional software.
Embed the Solunis engine into your existing app via SDK or API — without building from scratch.
Hindu, Islamic, Jewish, Christian, Buddhist, Sikh, Jain, Parsi, and more — correctly computed per tradition's calendar rules.
Official government holiday datasets for 190+ countries with subnational and state-level resolution.
Earth Day, World Water Day, Biodiversity Day, Climate Action Day — all UN-designated environmental observances tracked automatically.
Solunis detects your location and surfaces the right mix of local, national, and global observances in one view.
Solunis uses a deterministic astronomical computation model — the same class of algorithms used by observatories and space agencies — to deliver timing you can trust for rituals, legal documents, and institutional systems.
High-precision solar position derived from Julian Day number and century-scale correction terms.
Moon's ecliptic longitude computed using multi-term perturbation series for accurate phase angles.
Phase-angle difference divided into 30 Tithis and 27 Nakshatras with exact transition timestamps.
Solar and lunar positions projected into each calendar system's epoch and intercalation rules simultaneously.
All timing adjusted for geodetic coordinates, altitude, atmospheric refraction, and timezone offset.
Composite auspiciousness scores derived from the intersection of all five Panchanga elements.
The Solunis API helps developers and institutions embed astronomical calendar intelligence into their own applications without building it from scratch.
Every culture marks time by the same sun and the same moon. Solunis unifies humanity's diverse relationship with celestial cycles — not by homogenizing traditions, but by grounding each one in shared astronomical truth.
