What does the Vrat Calendar tool do?

Every major vrat with fasting rules, timings and mantras.

Is Vrat Calendar free to use on SanatanTools?

Yes — Vrat Calendar is free to use. Only long-form premium PDF reports require a subscription; every calculation shown on the page itself is free and needs no signup.

How accurate is Vrat Calendar?

Vrat Calendar runs on the same Swiss-ephemeris-grade calculation engine used across SanatanTools, with the Lahiri ayanamsa, your exact coordinates and IANA timezone — so results match professional Vedic software.

What else is available under Festival Tools?

Every Sanatan festival — dates, vrat rules, puja vidhi, katha, mantras and reminders. You can browse every Festival Tools tool from the /festivals category page.

How accurate is the Kundli generated by SanatanTools?

Charts are computed from Swiss-ephemeris-grade planetary positions with the Lahiri ayanamsa, your exact birth coordinates and IANA timezone — the same maths a professional astrologer's software uses.

What is the difference between the free and premium Kundli report?

The free report covers the core 6 pages — charts, planetary positions, basic dasha and a summary. The premium report expands this to 40+ pages with Mahadasha timelines, yogas and doshas, remedies, Sade Sati and year-ahead predictions.
