Make your own learning adventure

Open Pañcāṅga is a non-linear, choose-your-own-path learning environment. Begin with what interests you and choose another turn whenever a new question appears.

The three child explorers and Gajajī choose among winding forest paths leading toward different learning destinations.

Your guide stays nearby

Your Trail Compass keeps the next choices visible.

As you explore, one of your trail guides stays nearby with your Trail Compass, offering suggestions about what to see next. Open it to choose from six suggested moves, see the whole learning forest, or visit the Sky Explorer.

Open and close it: When the compass is closed, select the upward arrow to open it. When it is open, select the downward arrow in the same place to fold it closed and return to the page.

Follow a nearby idea

Move from tithi to pakṣa, lunar months, or a related observance.

Take a surprising turn

Occasional cross-forest suggestions expose less-traveled ideas.

See the whole forest

Open the visual index whenever you want every option at once.

Test an idea

Use a limited live sky check after a concept has made you curious.

Begin with something that matters to you

A familiar celebration can open a path into astronomy and Sanskrit.

People often become curious about the calendar when a cultural or religious occasion they enjoy is approaching. Begin with that occasion, then follow its date back to the sky: What is the Moon doing? Which tithi, pakṣa, or māsa is underway? Does sunrise, moonrise, or another time of day help place the observance on the calendar? The familiar occasion gives each new word a purpose.

Hindu, Buddhist, Jain, regional, family, and temple calendars may connect different names, teachers, deities, ancestral practices, fasts, and festivals with the same lunar landmark. Open Pañcāṅga explores one documented connection at a time, helping you understand both the shared sky and the different ways people use its natural clock.

The picture forms piece by piece

Specialized vocabulary becomes meaningful through relationships.

A term such as tithi becomes clearer when it connects with the Moon and Sun,pakṣa, local time, and an observance rule. Important words therefore reappear in different settings instead of being presented once in an isolated glossary.
