Q: What is the difference between Tithi and date?

A date follows the solar Gregorian calendar and is exactly 24 hours. A Tithi is a lunar unit based on the Moon's angular distance from the Sun, and its duration varies from about 19 to 26 hours. This means a Tithi can start midway through one date and end partway through the next.

Q: How reliable is the day quality score?

The score is based on classical Panchang rules from traditional Hindu almanac traditions. It considers Tithi, Nakshatra, Yoga, Karana, and special periods. While it provides a solid general guideline, specific muhurat (electional) analysis for important events should also consider your personal birth chart.

Q: Why do festival dates differ from other calendars I have seen?

Festival dates depend on the Tithi and regional conventions. Some traditions celebrate on the day the Tithi is active at sunrise, others when it is active during a specific window. Different Panchang publishers may also use slightly different ayanamsa values or calculation methods, leading to occasional one-day differences.

What Is a Vedic Monthly Calendar?

A Vedic monthly calendar (Panchang calendar) maps each day of the month with its five core astrological elements: Tithi (lunar day), Nakshatra (lunar mansion), Yoga (Sun-Moon combination), Karana (half-tithi), and Vara (weekday). Together, these five limbs determine the quality and character of every day.

Unlike a standard calendar that only tracks dates and holidays, a Vedic monthly calendar reveals which days are naturally favorable for important activities like ceremonies, travel, or starting new ventures — and which days call for caution. Festivals, fasting days, and special periods like Panchak and Bhadra are all marked based on these astronomical calculations.

How Does This Calendar Work?

For each day of the selected month, the tool computes the Sun and Moon positions using the Swiss Ephemeris, then derives all five Panchang elements from those positions. Tithi comes from the angular separation between Sun and Moon. Nakshatra is determined by the Moon's sidereal longitude. Yoga is calculated from the combined longitudes of both luminaries.

Each day receives a quality score based on the overall favorability of its Panchang elements. The calendar also flags special periods — Panchak (when Moon transits the last five Nakshatras), Bhadra (Vishti Karana, considered inauspicious), and festivals identified from traditional Hindu almanac rules.
