How to Get Hindu Calendar and Panchang Data as JSON

When building Indian calendar apps, astrology tools, festival pages, or regional date features, one common problem appears very quickly: normal Gregorian dates are not enough.

A Hindu calendar page usually needs more than day, month, and year. It may need Tithi, Nakshatra, Yoga, Karana, Vara, Paksha, sunrise, sunset, moon phase, and festival logic. These values can also change by location, because sunrise time and local calendar rules matter.

That is why using structured Panchang data through JSON is easier than manually maintaining static festival tables.

What data is usually needed?

A useful Panchang API response should include:

• Tithi
• Nakshatra
• Yoga
• Karana
• Vara
• Paksha
• Sunrise and sunset
• Moon data
• Festival information
• Location-based calculation

For example, a calendar app may need to answer a simple question:

What is the Hindu calendar date for this city on this Gregorian date?

But internally, that answer depends on astronomical calculations and traditional Panchang rules.

Why JSON helps developers

JSON makes the data easy to use in websites, mobile apps, dashboards, and backend services.

A frontend app can call an API and show the result directly. A backend system can store the response, compare dates, or generate monthly calendar views.

Example use cases:

• Hindu calendar websites
• Festival reminder apps
• Panchang widgets
• Astrology dashboards
• Regional calendar tools
• Date conversion features
• Educational calendar pages

Testing Panchang data live

I am building DevDarsha API for this exact use case. It provides Panchang and Hindu calendar data through structured JSON endpoints.

You can test a live Panchang response here:

Basic integration idea

A simple integration usually follows this flow:

1. Select a Gregorian date.
2. Select a city or location.
3. Send the request to the Panchang API.
4. Read the JSON response.
5. Display Tithi, Nakshatra, sunrise, sunset, and festival data in the app.

This keeps the application clean because the calendar logic stays inside the API layer instead of being hardcoded inside the frontend.

Final note

For small personal projects, static Hindu calendar data may be enough. But for apps that need city-based results, festival accuracy, or future date calculations, an API-based approach is easier to maintain.
