TithiTools

TithiTools is a versatile and precise .NET Core library for calculating Tithis, an essential aspect of Hindu and Vedic lunar calendar systems. Easily determine lunar phases and auspicious times for religious and cultural events. Flexible, efficient, and open source.

What is a Tithi?

A Tithi is a fundamental concept in Hindu lunar calendars. It represents a specific lunar day or phase of the moon and is a key element in determining auspicious times for religious and cultural events.

The image above illustrates the 12-degree angle of separation between the moon and sun, which is used in Tithi calculations.

Installation:

TithiTools is available as a nuget package from nuget.org

dotnet add package TithiTools

Examples

You can use the TithiTools library in your C# application to calculate Tithis for a specific date range.

// Calculate Tithis within a date range
var tithis = TithiTools.Calculator.FindTithiInDateRange(startDate, endDate);

// Filter Tithis by specific indices
var filteredTithis = TithiTools.Calculator.FindTithiInDateRange(startDate, endDate, indexFilter: new HashSet<int> { 11, 26 });

// Set custom precision
var precisedTithis = TithiTools.Calculator.FindTithiInDateRange(startDate, endDate, precision: 0.0001d);

// Calculate angle between the sun and moon at specific time
var angle = TithiTools.Calculator.GetAngle(dateTime);
