Angarki Chaturthi 2026: September 29 Vrat Katha Explains Why Ganesha’s Tuesday Fast Is Said to Ease Mangal Dosh

Angarki Chaturthi 2026: Date, Tithi and Moonrise

Angarki Chaturthi will be observed on September 29, 2026. In New Delhi, Krishna Chaturthi begins at around 5:10 PM on September 29 and continues until approximately 2:55 PM on September 30. The Moon is expected to rise at around 7:39 PM in Delhi, so devotees observing Sankashti can complete the fast after the evening puja and Moon-related rituals. Moonrise timings vary by location and should be checked according to the local panchang.

This Sankashti is also known as Vighnaraja Sankashti Chaturthi. The name Angarki comes from Angaraka, a traditional name associated with Mars.

What Is Angarki Chaturthi?

Sankashti Chaturthi is observed on Krishna Paksha Chaturthi and is dedicated to Lord Ganesha. Devotees traditionally fast during the day and complete the vrat after Moonrise.

When Sankashti Chaturthi falls on a Tuesday, it is called Angarki Chaturthi or Angarki Sankashti Chaturthi. Tuesday is associated with Mangal or Mars, while Ganesha is worshipped as the remover of obstacles. The combination is therefore considered especially significant in traditional Hindu practice.

The importance of the day comes primarily from the Angaraka-Ganesha vrat katha.

Angarki Chaturthi Vrat Katha: The Story of Angaraka and Lord Ganesha

According to the traditional account, Angaraka, associated with Mars, was a devoted worshipper of Lord Ganesha. He performed intense penance and prayed to Ganesha with deep devotion.

Pleased with his devotion, Lord Ganesha appeared before Angaraka and offered him a boon.

Angaraka did not ask for material wealth or power. Instead, he wished to have his name permanently associated with Lord Ganesha and sought a special place among devotees who worshipped Ganesha.

Ganesha granted his wish.

According to the traditional katha, Ganesha declared that the Chaturthi that falls on Tuesday would be associated with Angaraka and would therefore be known as Angarki Chaturthi. Devotees who observe the fast and worship Ganesha on this day are traditionally believed to receive special spiritual merit.

The story explains why a Tuesday Sankashti is regarded as particularly important among the monthly Ganesha vrats. Traditional accounts also associate the observance with the merit of multiple Sankashti vrats.

Why Is Angarki Chaturthi Linked to Mangal Dosh?

The connection with Mangal Dosh comes from the association of Tuesday with Mangal or Mars.

In Vedic astrology, Mars is known as Mangal, Angaraka or Bhauma. Mangal Dosh is an astrological concept traditionally associated with certain placements of Mars in a birth chart.

Because Angarki Chaturthi combines:

• Lord Ganesha, who is traditionally worshipped for removing obstacles
• Chaturthi vrat, which is dedicated to Ganesha
• Tuesday, associated with Mars
• Angaraka, the name connected with Mars

some Hindu and astrological traditions recommend Ganesha worship and Angarki fasting as a spiritual practice for those seeking relief from the effects associated with Mangal Dosh.

The belief is that worshipping Ganesha on a day connected with Mangal creates a devotional route for pacifying Mars-related influences. This is a religious and astrological belief rather than a scientifically established effect or a guaranteed method of changing a horoscope.

How to Observe Angarki Chaturthi Vrat on September 29

Devotees traditionally follow these steps:

1. Take a vrat sankalp in the morning after bathing and remembering Lord Ganesha.
2. Observe a fast according to one's health, family tradition and capacity.
3. Worship Lord Ganesha in the evening with flowers, durva grass, fruits and other customary offerings.
4. Offer modak or another suitable naivedya to Ganesha.
5. Recite the Ganesha mantra, Ganapati Atharvashirsha or Ganesha stotra according to one's tradition.
6. Wait for Moonrise and offer arghya after seeing the Moon.
7. Complete the vrat and have the permitted meal after the evening rituals.

For New Delhi, Moonrise on September 29 is around 7:39 PM. Since Moonrise differs from city to city, devotees should follow the timing applicable to their location.

Which Ganesha Mantra Can Be Chanted on Angarki Chaturthi?

A simple mantra commonly used during Ganesha worship is:

ॐ गं गणपतये नमः।

Om Gam Ganapataye Namah.

Devotees seeking to focus their prayer on Mangal-related concerns may also worship Ganesha with the intention of removing obstacles, gaining clarity and seeking balance rather than treating the vrat as a guaranteed remedy for a horoscope condition.

What Makes September 29, 2026 Special?

September 29 is not an ordinary Sankashti Chaturthi because it falls on Tuesday, making it Angarki Sankashti Chaturthi.

There is also a date-related point that may cause confusion. On September 29, Chaturthi begins only around 5:10 PM, after Tritiya ends. However, the Moon rises later that evening while Chaturthi is still running. Since Sankashti observance is tied to the Moonrise, September 29 is the relevant fasting day in Delhi.

This is why some calendar displays may show September 30 when looking only at the tithi present at sunrise, while Sankashti observance falls on September 29.

Angarki Chaturthi and Mangal Dosh: What the Vrat Symbolises

The deeper significance of the vrat is the traditional connection between Ganesha's obstacle-removing role and Mars' fiery energy.

Mangal is associated in Vedic astrology with qualities such as courage, action and force. When Mars is considered problematic in a horoscope, traditional remedies focus on disciplined worship and practices intended to pacify its influence.

Angarki Chaturthi brings this symbolism together through the worship of Ganesha on Tuesday. Therefore, devotees who believe they have Mangal Dosh may observe this vrat as part of their traditional spiritual practices.

However, one Angarki Chaturthi fast should not be presented as a guaranteed cure for Mangal Dosh. The astrological interpretation of Mangal Dosh itself depends on the complete birth chart, and different traditions use different rules for identifying and assessing it.
