The origin of Ekadashi (also spelled Ekadasi) is rooted in Hindu religious tradition and is described in several ancient texts. There is no historical evidence for a single date when the observance "started"; instead, it appears to have developed over many centuries within the broader practice of Hindu fasting and lunar rituals.
Scriptural origin
According to the Padma Purana, Ekadashi originated during a battle between Lord Vishnu and the demon Mura.
The story says:
Vishnu was fighting the powerful demon Mura.
While resting in a cave, Vishnu was attacked by Mura.
From Vishnu's divine energy emerged a radiant maiden who defeated the demon.
Vishnu named her Ekadashi, because she appeared on the 11th lunar day (Ekadashi tithi) of the waxing fortnight.
He declared that those who fast and worship on Ekadashi would receive spiritual merit and purification.
This is the traditional religious explanation for the observance.
Historical development
From a historical perspective:
Fasting on specific lunar days was already practiced during the Vedas period (roughly 1500–500 BCE), although the Ekadashi fast itself is not described there in its later form.
By the time of the Mahabharata (compiled roughly between 400 BCE and 400 CE), fasting and devotion to Vishnu on Ekadashi had become established.
The Puranas (especially the Padma Purana, Bhavishya Purana, and Skanda Purana) greatly expanded the stories, rules, and spiritual significance of Ekadashi between about the 4th and 12th centuries CE.
During the medieval Bhakti movement, Ekadashi became one of the most widely observed fasting days among devotees of Vishnu and Krishna.
Why it is observed twice a month
The Hindu lunar month has two fortnights:
Shukla Paksha Ekadashi – the 11th day of the waxing moon.
Krishna Paksha Ekadashi – the 11th day of the waning moon.
This results in about 24 Ekadashis each year, with one or two additional Ekadashis in years that include an extra lunar month (Adhika Masa).
Summary
Traditional belief: Ekadashi began when Vishnu created the goddess Ekadashi, who defeated the demon Mura, as described in the Padma Purana.
Historical view: The practice evolved gradually from ancient Hindu lunar fasting traditions and became well established by the early centuries CE, with later Puranic texts giving it its familiar mythology and ritual significance.

The 15-day waxing and waning lunar cycles have been important in many religions and cultures, but daily observances for every lunar day are most fully developed in Hinduism. Other religions generally emphasize a smaller number of significant lunar dates rather than every day of the cycle.
Here's an overview:
Hinduism: the most detailed lunar calendar
Each lunar fortnight (Paksha) has 15 tithis(lunar days). Many families, especially women, observe fasts or perform worship on specific tithis.
Pratipada (1st): Beginning of the lunar fortnight; in some regions associated with prosperity rituals.
Dwitiya (2nd): Festivals such as Bhai Doojoccur on this tithi in certain months.
Tritiya (3rd): Akshaya Tritiya, Hartalika Teej(in specific months); women pray for marital happiness.
Chaturthi (4th): Dedicated to Ganesha; Sankashti Chaturthi and Vinayaka Chaturthifasts.
Panchami (5th): Nag Panchami and Vasant Panchami (month-dependent).
Shashthi (6th): Worship of Kartikeya or regional mother goddesses.
Saptami (7th): Ratha Saptami, dedicated to Surya.
Ashtami (8th): Durga Ashtami, Krishna Janmashtami (depending on the month).
Navami (9th): Rama Navami, Maha Navami.
Dashami (10th): Vijayadashami (Dussehra).
Ekadashi (11th): Fasting dedicated to Lord Vishnu.
Dwadashi (12th): Breaking the Ekadashi fast.
Trayodashi (13th): Pradosh Vrat for Shiva; Dhanteras in one month.
Chaturdashi (14th): Maha Shivaratri and Naraka Chaturdashi occur on this tithi in specific months.
Purnima (15th of waxing): Full Moon festivals such as Guru Purnima, Holi, Buddha Purnima, Sharad Purnima, Kartik Purnima.
Amavasya (15th of waning): New Moon; ancestor remembrance, Diwali (in one month), and Somvati Amavasya when it falls on a Monday.
Women's observances in Hinduism
Many fasts traditionally observed by women are linked to particular tithis, though men may also observe them. Examples include:
Teej
Karva Chauth
Vat Savitri
Hartalika Teej
Varalakshmi Vratam
Sankashti Chaturthi
Jaya Parvati Vrat
Savitri Amavasya
The specific customs vary greatly by region, family tradition, and community.
Other religions
Buddhism: The main lunar observance is the Uposatha day, usually on the New Moon, Full Moon, and quarter moons. Lay followers may undertake extra precepts, meditate, and visit temples.
Jainism: Fasting on Ashtami, Chaturdashi, Purnima, and Amavasya is common, with especially important observances during Paryushana.
Islam: The Islamic calendar is entirely lunar, but worship is generally tied to months rather than moon phases. There are no prescribed observances for each day of the waxing or waning cycle.
Judaism: Rosh Chodesh (the New Moon) marks the beginning of each month. It has a long-standing association with women in Jewish tradition, and some communities hold special prayers or gatherings.
Conclusion
Among the world's major religions, Hinduism has the most elaborate system of observances tied to nearly every lunar day (tithi). Other traditions also use the moon to determine sacred times, but they generally focus on specific lunar phases or festivals rather than assigning distinct religious practices to each of the 15 waxing and 15 waning lunar days.

There has long been interest in whether human biology—especially menstruation, mood, and sleep—is linked to the lunar cycle. Here's what traditional beliefs and modern science say.
Menstruation and the lunar cycle
Traditional beliefs
Many cultures have associated menstruation with the Moon because:
The average menstrual cycle is about 28 days (though the normal range is roughly 21–35 days).
A lunar month (new moon to new moon) is about 29.5 days.
This similarity led to symbolic connections in traditions including Hinduism, some Indigenous cultures, ancient Greek beliefs, and modern spiritual practices. Some traditions associate:
New Moon with menstruation and inward reflection.
Full Moon with fertility, ovulation, or abundance.
These are cultural and spiritual interpretations rather than established biological facts.
Medical evidence
Current research shows:
Most menstrual cycles do not consistently synchronize with the Moon.
A small number of studies have found weak or temporary associations in some individuals, but results are inconsistent and do not demonstrate a universal biological link.
Menstrual timing is primarily regulated by hormones produced through the hypothalamic–pituitary–ovarian (HPO) axis, not by the Moon.
Men and the lunar cycle
Men do not have a monthly reproductive cycle comparable to menstruation.
Hormones such as testosterone follow:
A daily (circadian) rhythm, often highest in the morning.
Longer-term fluctuations due to age, health, stress, sleep, illness, and lifestyle.
There is no established 15-day or 29.5-day hormonal cycle in men comparable to the menstrual cycle.
Psychological and medical conditions
Some researchers have explored whether lunar phases influence health, but the evidence is mixed.
Conditions that have been studied include:
Sleep quality
Mood changes
Anxiety
Depression
Bipolar disorder
Epileptic seizures
Migraine
Emergency department visits
Birth rates
Overall, high-quality studies generally find little or no consistent effect of lunar phases on these conditions.
Circadian and seasonal rhythms
Scientists recognize several biological rhythms:
Circadian rhythm: approximately 24-hour cycle controlling sleep, hormones, body temperature, and alertness.
Circalunar rhythm: approximately monthly rhythms. These are well established in many marine animals, but evidence in humans is limited.
Circannual rhythm: yearly changes affecting physiology and behavior, influenced by seasons and daylight.
In traditional Hindu thought
Traditional Hindu calendars use:
The Sun (Surya) for seasons and the solar year.
The Moon (Chandra) for months, tithis(lunar days), fasting, and festivals.
Some traditional systems such as Ayurveda and yoga describe the Moon as influencing the body's fluids, emotions, and mental state. These ideas are part of traditional philosophy and should not be understood as medically established mechanisms.
Summary
The similarity between the menstrual cycle (~28 days) and the lunar month (~29.5 days) has inspired many cultural and spiritual beliefs.
Modern medicine has not confirmed a consistent biological link between menstrual cycles and the phases of the Moon.
Men do not have a recognized monthly hormonal cycle linked to lunar phases.
Human biology is strongly governed by circadian (24-hour) rhythms, while evidence for circalunar rhythms in humans remains limited and is an active area of research.

Circadian and circa lunar rhythm in males and effects on brain body mind reproductive system
ChatGPT said:
Humans have several biological rhythms that affect the brain, body, and reproductive system. The circadian rhythm (about 24 hours) is well established in males. A circalunar rhythm (about 29.5 days) is clearly present in many marine animals, but in humans—including males—the evidence is much weaker and not considered a primary biological clock.
1. Circadian rhythm (24-hour cycle)
The circadian rhythm is controlled by the brain's suprachiasmatic nucleus (SCN) in the hypothalamus. Light entering the eyes synchronizes this internal clock.
Brain
Regulates sleep and wakefulness.
Influences attention, memory, learning, and reaction time.
Affects emotional regulation and mood.
Coordinates hormone release.
Hormones
Daily hormone patterns in healthy men include:
Melatonin: rises after sunset, promoting sleep.
Cortisol: peaks in the early morning, supporting alertness.
Testosterone: highest in the morning and declines through the day.
Growth hormone: released mainly during deep sleep.
Body
The circadian rhythm influences:
Body temperature
Blood pressure
Heart rate
Liver metabolism
Digestion
Immune function
Muscle strength and physical performance
Reproductive system
Healthy sleep and circadian alignment support:
Testosterone production
Sperm production (spermatogenesis)
Sexual desire (libido)
Erectile function
Chronic sleep deprivation or night-shift work has been associated with lower testosterone, reduced sperm quality, and impaired fertility.
2. Circalunar rhythm (about 29.5 days)
Scientists have looked for monthly rhythms in humans, but the evidence is mixed.
Some small studies have reported possible changes in:
Sleep duration
Melatonin levels
Mood
Physical activity
However:
Results are inconsistent.
Many studies find no meaningful relationship.
No established monthly hormonal cycle comparable to the menstrual cycle has been identified in men.
Because of this, mainstream medicine does not currently recognize a biologically important circalunar reproductive rhythm in males.
3. Other biological rhythms in males
Besides circadian rhythms, men experience:
Ultradian rhythms
These are cycles shorter than 24 hours (often 90–120 minutes) and influence:
Stages of sleep
Cycles of alertness and fatigue
Pulses of hormone release
Circannual rhythms
These occur over the course of a year and may involve small seasonal changes in:
Testosterone
Sperm quality
Mood
Vitamin D status (depending on sunlight exposure)
The magnitude of these changes varies and is influenced by geography and lifestyle.
4. Effects of circadian disruption
When the circadian system is disrupted—for example by shift work, jet lag, or chronic sleep loss—it can affect:
Brain
Reduced concentration
Poor memory
Slower decision-making
Increased risk of anxiety and depression
Body
Weight gain
Increased risk of type 2 diabetes
Higher blood pressure
Increased cardiovascular risk
Impaired immune function
Reproductive health
Lower testosterone
Reduced sperm count and motility
Lower fertility
Decreased libido
5. Traditional perspectives
In traditions such as Ayurveda and yoga:
The Sun is associated with activity, heat, metabolism, and vitality.
The Moon is associated with cooling, rest, emotions, and nourishment.
Practices such as meditation, breathing exercises, fasting, and aligning daily routines with sunrise and sunset are intended to support overall health. These ideas are part of traditional systems and are not equivalent to modern physiological models, though some practices (such as maintaining regular sleep schedules and getting morning light) are supported by contemporary research.
Key takeaway
Circadian rhythms have strong scientific evidence and significantly influence the male brain, hormones, metabolism, sleep, and reproductive health.
Circalunar rhythms in human males remain an area of ongoing research. While some studies suggest subtle effects in certain individuals, there is no consensus that men have a monthly lunar-linked biological cycle comparable to the female menstrual cycle.
