Tithi

Tithi in Panchang – Meaning, Today’s Tithi & Hindu Lunar Day Calendar

A Tithi represents a lunar day and is determined by the position of the Moon at the time of sunrise. It can be understood as the lunar phase that is predominant at the beginning of the day. In traditional Indian timekeeping, the day’s Tithi is identified based on which lunar phase is active at sunrise, even though the Moon continues to move and the Tithi may change during the course of the day.

The Panchang, which serves as a religious and calendrical guide, clearly indicates when the Tithi active at sunrise will end. In other words, although a particular Tithi is assigned to the day based on the Moon’s position at sunrise, it does not necessarily last for the entire solar day. Because the Moon is constantly moving relative to the Sun, Tithis changes dynamically.

In this process, the lunar phases - meaning the waxing and waning of the Moon, play a crucial role. For example, during the waxing phase (Shukla Paksha), when the visible portion of the Moon increases, the tithis progress in sequence toward fullness. During the waning phase (Krishna Paksha), when the Moon gradually decreases in visible size, the tithis continue in sequence toward the new moon. Thus, a tithi is not merely a marker of a calendar day; it reflects the dynamic motion of the Moon and the evolving relationship between the Sun and the Moon. For this reason, the calculation and understanding of Tithi are important from religious, cultural, and even astronomical perspectives.

A Tithi represents a lunar day or a specific phase of the Moon within a lunar month. In the Panchang system, a lunar month, generally consisting of approximately four weeks - is referred to as a Chandra Maas. Since the calculation of Tithi is based on the relative positions of the Moon and the Sun, the traditional calendar is often described as a “lunisolar calendar.”

What is Tithi in Vedic Astrology?

In simple terms, a Tithi is defined as the 12-degree angular distance between the Sun and the Moon. The entire zodiac circle measures 360 degrees. When these 360 degrees are divided into 30 equal parts, each part measures 12 degrees — and each 12-degree segment is known as one Tithi.

This means that whenever the Moon moves 12 degrees away from the Sun, one Tithi is completed. As the Moon continues to move forward in its orbit, the angular distance increases and the Tithi changes accordingly.

It is important to understand that a Tithi is not equal to a solar day (24 hours). The Moon does not move at a uniform speed; sometimes it travels faster and sometimes slower. Because of this variation, a Tithi may last around 19 hours on some occasions and up to 26 hours on others. This is why sometimes two Tithis can fall within a single calendar day, and in rare cases, a Tithi may even be skipped (known as Kshaya Tithi).

In Vedic astrology, a Tithi is considered an expression of lunar energy. Since the Moon is regarded as the significator of the mind, emotions, and psychological tendencies, Tithi is deeply connected with one’s mental and emotional state.

How is Tithi Calculated?

The calculation of Tithi is entirely based on astronomical mathematics. It is not merely a religious belief, but a precise astrological computation derived from the actual positions of the Sun and the Moon in the zodiac.

Calculation Formula:

Tithi = (Current Degree of Moon – Current Degree of Sun) ÷ 12°

For example, if the Sun is positioned at 20° and the Moon is at 44°, the angular difference between them is 24 degrees.

24 ÷ 12 = 2

This indicates that the second Tithi (Dwitiya) is running.

In this way, every time the angular distance between the Sun and the Moon increases by 12 degrees, a new Tithi begins

Importance of Tithi in Panchang

The Hindu Panchang is not merely a tool for indicating dates; it is a system designed to understand the spiritual quality of time. One of the primary foundations of this system is the Tithi . A Tithi indicates the lunar influence of a particular day and determines which activities are considered auspicious or inauspicious on that day.

What Does a Tithi Represent?

A Tithi is based on the angular distance between the Sun and the Moon. Every time this distance increases by 12 degrees, a new Tithi begins. For this reason, a Tithi does not have a fixed duration of 24 hours; it may sometimes be shorter or longer.

This is why, in the Panchang, auspicious activities are not decided solely by the English calendar date. Instead, primary importance is given to the Tithi.

30 Tithis of the Hindu Panchang – Meaning, Deity and Astrological Significance

There are 30 Tithis in a lunar month, and each carries its own significance. Tithis are traditionally classified as auspicious or inauspicious, and this classification is organized into five categories:

1. Nanda (Auspicious) - This category includes Tithis considered especially favorable. It includes Pratipada (1st), Shashthi (6th), and Ekadashi (11th). These days are generally regarded as suitable for positive beginnings and religious observances.
2. Bhadra (Health & Well Being) - Tithis in this category are associated with health and welfare. It includes Dwadashi (12th), Dwitiya (2nd), and Saptami (7th). These days are often considered supportive for activities related to healing and well-being.
3. Jaya (Victory) - These tithis symbolize victory and success. It includes Tritiya (3rd), Ashtami (8th), and Trayodashi (13th). They are often considered favorable for overcoming obstacles and achieving goals.
4. Rikta (Loss or Emptiness) - This category includes tithis that are traditionally regarded as less favorable or negative. It includes Chaturthi (4th), Navami (9th), and Chaturdashi (14th). These days are often avoided for major new beginnings.
5. Purna (Full Moon or New Moon) - This category refers particularly to the days of Purnima (Full Moon) and Amavasya (New Moon). It includes Panchami (5th), Dashami (10th), and Amavasya/Purnima. These days hold special spiritual and ritual importance.

Types Of Tihti Shukla and Krishna Paksha

According to the lunar phases, the lunar month is divided into two parts

Shukla Paksha - This phase represents the period when the Moon is increasing in size, moving from the new moon toward the full moon. The tithis in this phase range from Pratipada to Purnima (Full Moon). Shukla Paksha is generally considered auspicious, and many religious ceremonies, rituals, and worship practices are performed during this period.

Krishna Paksha - This phase represents the period when the Moon gradually decreases in size, moving from the full moon toward the new moon (Amavasya). The Tithis in this phase range from Purnima to Amavasya. Krishna Paksha is often regarded as comparatively less auspicious for material undertakings, but it is considered especially suitable for meditation, introspection, and spiritual practices.

Importance of Tithi in the Birth Chart

The Tithi prevailing at the time of birth is called the Janma Tithi (Birth Tithi). It plays an important role in understanding a person’s psychological framework, emotional tendencies, and karmic direction in life.

Since the Moon represents the mind in Vedic astrology, and Tithi is directly based on the Moon’s relationship with the Sun, the Birth Tithi reflects a person’s inner nature and emotional structure.

For example:

• A person born on Ekadashi may naturally incline toward spirituality, devotion, or introspection.
• Someone born on Navami may exhibit courage, boldness, and strong determination.
• A person born on Ashtami may possess intense emotions and a powerful personality.

In astrological analysis, it is not sufficient to consider only the zodiac sign (Rashi). The Tithi also plays a significant role in shaping an individual’s character and life experiences.

In this way, the combined framework of tithi, Shukla Paksha, and Krishna Paksha plays a significant role in religious and cultural life. Each tithi and each lunar phase carries its own distinct meaning and importance, shaping rituals, festivals, and the traditional understanding of time.
