How this tool works and how to read it
Festival Calendar turns calculated Panchang states into rule-based festival date suggestions for the selected year and location. Instead of storing a single hand-written list, AstroVedic360 evaluates the relevant Tithi or other implemented condition against the local civil day and shows the rule basis beside the candidate date. This is important because many observances depend on whether a lunar condition prevails at sunrise, moonrise, sunset, Nishita or another defined part of the day.
A festival date is not always globally identical. Timezone, local sunrise and regional precedence can move an observance by one civil date even though the underlying astronomical transition is the same. The calendar therefore keeps the selected location visible and describes its output as a calculated suggestion when the broader regional decision tree is not fully encoded.
How to read the result
Start with the year and location. Scan the candidate list, then read the reason shown for each festival. The reason tells you which implemented Panchang condition selected that date rather than asking you to trust a date with no explanation.
For important observances, compare the candidate with the Daily Panchang for the same date. That lets you inspect the Tithi, Nakshatra and transition timing directly. Festival rules that depend on moonrise, sunset, Nishita or Aparahna should be checked against the corresponding timing tool when available.
If a temple, regional Panchang or family tradition follows a different precedence rule, use that tradition for observance. AstroVedic360 does not claim that one encoded rule can replace every regional calendar.
Verified example: Hyderabad Ugadi date, 19 March 2026
AstroVedic360’s existing Ugadi regression case identifies 19 March 2026 as the Hyderabad Chaitra-year anchor. The test follows the calculated lunar-month and Shukla Pratipada context rather than placing a fixed festival date into the calendar. This example demonstrates a verified reference case, not a rule for every year or every locality.
To investigate a disagreement, use the same civil date and city in Daily Panchang, then compare the Tithi transition and the regional observance rule. The Festival Calendar’s more limited candidate list must not be mistaken for a complete regional festival authority.
Methodology and limits
Festival candidates are derived from the same calculated Panchang engine used elsewhere on AstroVedic360, which reduces the risk of one page using different Tithi data from another. Each implemented festival rule remains traceable to its stated time anchor or Panchanga condition.
Regional Panchang authorities can use additional precedence, Kshaya/Vriddhi, Smarta/Vaishnava or temple-specific rules. Where those are not implemented, the calendar labels the result as a suggestion instead of presenting false certainty.
Frequently asked questions
Why can my local festival date differ from another website?
Different sites may use different locations, sunrise rules, regional precedence or tradition-specific conventions. Check the stated method before comparing dates.
Are festival dates copied from a static list?
The supported candidates are derived from calculated Panchang conditions and the implemented rule basis for the selected year and location.
Should I follow the site or my temple calendar?
For observance, follow the regional, temple or family tradition you rely on when its rule differs from the site’s disclosed implementation.
Can I verify a candidate date?
Yes. Open the Daily Panchang for the same date and location to inspect the underlying Tithi, Nakshatra and timing context.
