Vedic Sciences

Old knowledge, explained clearly and checked with care.

For thousands of years people in India have planned their days, homes and towns by the Sun, the Moon and the land.

Kalyaan explains this knowledge in simple words, checks what can be measured, and turns it into free tools, starting with our Moon Calendar.

Why it matters

Old knowledge still shapes daily life.

Fasts, festivals, weddings and Jain parva days still follow the moon date. Many families think of Vastu when they build a home or an office.

Yet clear and reliable explanations are hard to find. Kalyaan wants this knowledge to be easy to understand, accurate and free for everyone.

Respect for tradition. Care for accuracy.
How we work

From old knowledge to useful tools.

We take one subject at a time and follow the same simple path.

  1. 1

    Learn

    Study the traditional rules and where they come from.

  2. 2

    Explain

    Write them in plain Hindi and English.

  3. 3

    Check

    Test what can be measured, such as the times of the Moon, against reliable sources.

  4. 4

    Share

    Turn it into free articles and tools anyone can use.

What we explore

Time, space and tradition.

Vedic sciences cover a wide field. We begin with the subjects people use in daily life.
