MeasuredSunrise and sunset outputs validated for presence, ordering, and daily calculation integrity across every launch-corpus profile-day.
56,252 / 56,252 checks passed (100%).
Release validation passed across every covered section.
DevDarsha Engine v5.0.0 completed the 2020–2030 launch-corpus sweep with a 100% pass rate across the covered deterministic validation sections.
Engine v5.0.0 is production-ready for deterministic panchang generation across the 2020-2030 launch corpus, with 100% pass rate on structural, range, ordering, muhurat, choghadiya, and festival-emission invariants across 28,126 profile-days.
Snapshot, not a live metric. The figures on this page are a release-validation snapshot as of 2026-05-10. Future snapshots may change as coverage expands. The Panchang API is provided "as is" with reasonable care; please independently verify outputs before relying on them for legal, financial, medical, ceremonial, or other high-risk decisions.

What “accuracy” means here. We publish a verifiable public manifest with a SHA-256 integrity hash. It summarizes the release-validation result for the 2020–2030 launch corpus without exposing internal implementation artifacts. Open the manifest at /accuracy-manifest.
Verification Layers
Each output category is validated independently using the most appropriate reference method for that domain. Learn how we validate.
Panchang Elements
MeasuredTithi, Nakshatra, Yoga, and Karana validated for range, naming, paksha where applicable, and sunrise-based calculation integrity.
112,504 / 112,504 checks passed (100%).
Vrat & Lunar Events
MeasuredLunar-event context is validated through the same deterministic panchang and festival-emission release gates used by the daily engine.
Covered by panchang and festival validation gates.
Festival Dates
MeasuredFestival emissions validated for stable daily execution, required identifiers, names, lunar-month context, and valid public response shape.
28,126 / 28,126 profile-days passed (100%).
Muhurat Timings
MeasuredRahu Kaal, Gulika Kaal, Yamaganda, required muhurat windows, and Choghadiya slots validated for ordering and internal consistency.
56,252 / 56,252 checks passed (100%).
Calendar Coverage
Daily responses expose supported calendar systems directly. Unsupported systems are not implied by festival or nakshatra naming.
Supported: Vikram Samvat Supported: Shaka Samvat Supported: Bengali calendar Supported: Hijri, tabular Kuwaiti, +/- 1-2 days Additional calendar systems may be added after verification. Unsupported systems are not implied unless explicitly declared in the API response.
Release Gate
Every engine release is gated on a full accuracy regression before deployment. No update ships unless it passes all existing test cases, and new test cases are added with every release cycle.
