Sources & Methodology

Transparent Documentation on Calendar Sourcing, Geographic Modeling, and Data Classification

1. Data Provenance & Repository Scope

KalnirnayOnline.com is an independent digital calendar reference site. Information presented on this website is drawn directly from our repository dataset in data/calendar-events-2026.json, which documents date listings, English and Marathi festival titles, and verification status tags for 2026.

This platform is completely independent and is not affiliated with, endorsed by, or connected to Sumangal Press or the printed Kalnirnay calendar publication.

2. Reference Location

The default reference location specified for events and timings within our dataset is:

Primary Reference City: Pune, Maharashtra, India
Latitude: 18.5204° N
Longitude: 73.8567° E
Time Zone: Indian Standard Time (IST, UTC+5:30)

Timings and observances naturally vary depending on geographic location and distance from this reference coordinate.

3. Panchang Calculation Notice

This website does not currently calculate daily Panchang values (such as tithi start/end times, nakshatra, yoga, or karana). The calendar provides date-level festival and public holiday listings as documented in our repository dataset.

4. Data Review Status Codes

To provide full transparency, all entries in data/calendar-events-2026.json are cataloged with one of three review status designations:

verified: The observance date corresponds to a standard fixed calendar date or recognized civil holiday.
requires_review: Conflicting dates exist across regional traditions; further review is required.
unverified: Tentative observance date derived from preliminary calendar data awaiting independent verification.

5. Important User Advisory & Feedback

This website is intended for informational reference and general educational awareness. When planning life milestones, weddings, housewarmings, or religious ceremonies, users should always cross-verify dates and muhurat windows with an authorized family priest (Guruji) or a verified regional Panchang.
