Hanuman Jayanti: the Tithi, Not One National Clock Time

The civil date of a tithi moves every year, and it can differ between cities because a tithi is a portion of the Moon's elongation from the Sun, tied to local sunrise. Chaitra Shukla Purnima is the bright-fortnight full moon. Chaitra Krishna Dashami is the tenth tithi of the following dark fortnight. Both are called Hanuman Jayanti in living practice. A website that prints one morning hour for the whole country has chosen one region and one city and hidden the choice. If you need a muhurta, you need the panchang of your place for that year: tithi, nakshatra, and the lagna at the hour you will actually worship.

The five limbs are tithi, vara, nakshatra, yoga, and karana. For a vrata, the tithi current at sunrise is the classical test of which civil day owns the observance. An evening hour can belong to the next tithi. That is why a full-moon festival sometimes looks, on a clock, like it falls on two dates. Hanuman is linked in worship with Mars and with Tuesday, Mars's vara, which is a devotional association and not a claim that the jayanti must fall on a Tuesday. If the Purnima is a Friday, the jayanti is still the Purnima. Do not move the tithi to force a Tuesday.

People born on the jayanti have whatever lagna the hour produced. The festival does not place Mars in the 1st. A Mangal dosha is Mars in listed houses in the natal chart, not a birthday shared with a festival. If you are choosing an hour for a recitation, use the local panchang. If you are reading a life, use the birth lagna. Jyothish SI's lagna depends on the city offset. So does the local sunrise that decides the tithi. Neither is a single number for a nation.
