In brief: Ayurveda Day is observed on 23 September because a fixed calendar date is far easier to plan around than a lunar one, and because 23 September sits beside the autumnal equinox, when daylight and darkness are close to equal. The observance began in 2016 on Dhanteras, a lunar date that moved each year between October and November.
Ayurveda Day on 23 September: the short version
Ayurveda Day on 23 September is a public education date rather than a festival. It carries no prescribed ritual and no obligation. Its purpose is to give Ayurveda a dependable place in the calendar, so that lectures, community events, clinic open days and private reading can all be arranged well in advance.
For its first years the observance followed the lunar calendar. It now falls on 23 September every year. Two arguments sit behind that decision. The first is practical: a fixed date can be scheduled. The second is symbolic: 23 September falls beside the autumnal equinox, the moment when day and night are almost equal in length, which reads as a natural image of balance.
If you are meeting this subject for the first time, our beginner's guide to Ayurveda is a better starting point than the history of the date itself.
From Dhanteras to a fixed date
Ayurveda Day was first observed in 2016 on Dhanteras, the thirteenth lunar day associated with Dhanvantari. Choosing Dhanteras placed the observance inside an established cultural moment and gave it immediate recognition among people who already kept that calendar.
The difficulty was arithmetic rather than cultural. Dhanteras is set by the lunar calendar, so its position in the Gregorian year moves. In practice the observance drifted across a window of several weeks in October and November, and the exact date differed every year.
Why a moving date became difficult
A date that moves is a date that cannot be booked. The groups most likely to mark Ayurveda Day are also the groups that plan furthest ahead:
- Universities and colleges fix teaching timetables many months before a term begins.
- Professional associations schedule continuing education and conferences a year or more in advance.
- Clinics and practitioners arrange open days, talks and patient education around a fixed diary.
- Public bodies and libraries commission exhibitions and reading programmes on annual cycles.
- International audiences, including most readers in Europe, do not follow the lunar calendar in daily life and had to look the date up each year.
None of this made the observance impossible. It simply made a shared, repeatable programme harder to build.
Why Ayurveda Day is observed on 23 September
In 2025 the Government of India notified 23 September as the annual date for Ayurveda Day. The change separates the public education date from the festival calendar and gives the observance a single, memorable position in the year.
The practical argument
A fixed date is a planning instrument. Once 23 September is known to be the date in every year, a school can put it in the syllabus, an association can build a standing annual programme, and a reader can decide in January what they intend to study in September. The date stops being something to check and becomes something to rely on.
This matters more outside India than inside it. A reader in Lisbon, Amsterdam or Zagreb is unlikely to keep a lunar calendar to hand, and an observance that has to be looked up is an observance that is easily missed.
The symbolic argument: the equinox
The official explanation from the Ministry of Ayush also points to the autumnal equinox, which falls within a day or so of 23 September. At the equinox the hours of daylight and darkness are close to equal.
The symbolism is deliberately simple. Ayurveda is organised around the idea of balance: balance within the person, balance in the daily routine, and balance between a person and the surroundings they live in. An astronomical moment of near equality is an easy image to hold, and it requires no specialist knowledge to understand.
The equinox is also a genuine turning point in the European year. Evenings shorten quickly, the air becomes drier and cooler, and daily habits change whether or not anyone plans them. That makes late September a sensible time to look again at a routine.
What the change does not mean
Three misreadings are worth setting aside.
First, the new date does not cancel Dhanteras or diminish the figure of Dhanvantari. Dhanteras continues on its own calendar with its own meaning. What has happened is a separation of two different things: a cultural festival and a public education date.
Second, the date makes no claim about Ayurveda working differently on one day of the year. Nothing in classical Ayurveda ties practice to a single calendar date. The classical texts are concerned with daily rhythm and seasonal rhythm, not with anniversaries.
Third, a fixed international date does not replace regional or local observances. Communities that mark Ayurveda in other ways are free to continue exactly as before.
Balance is the idea the date points to
If the equinox supplies the image, balance supplies the subject. A few classical terms make the idea concrete, and they are worth knowing before any practice or product is considered.
Ayurveda describes the working of body and mind through three Dosha (functional principles that govern movement, transformation and structure). These are Vata (the principle of movement), Pitta (the principle of transformation) and Kapha (the principle of cohesion and structure). Every person carries all three, in a proportion of their own.
That personal proportion is called Prakriti (the constitution a person is born with). It does not change. What does change is Vikriti (the present state, which may have drifted away from the constitution). Classical practice is concerned with the distance between the two, which is why two people with the same complaint may be advised quite differently.
Two further terms appear constantly. Agni (the digestive and metabolic capacity) describes how well the body processes what it receives. Ojas (the classical term for vitality and resilience) describes the quality that careful living is said to protect. The classical compendia, among them the Charaka Samhita and the Ashtanga Hridayam, return to these ideas repeatedly.
A short introduction to the three doshas is the most useful single piece of background reading for the day.
Ritucharya (the seasonal routine) at the turn of autumn
The equinox connection is not purely decorative: classical Ayurveda has a dedicated subject for seasonal adjustment. The Ashtanga Hridayam and the Charaka Samhita both give the change between seasons more attention than the settled middle of a season, on the reasoning that weather turns quickly while a person adapts slowly.
In the European autumn the qualities that increase are dryness, coolness, lightness and irregularity. In classical language these are the qualities associated with Vata. The traditional response is the opposite set: warmth, moisture, steadiness and regular hours.
In practice that tends to mean warm cooked food rather than cold and raw, mealtimes at consistent hours, earlier evenings, and Abhyanga (the classical practice of massaging the body with warm oil) as a settling daily or weekly habit. Our guide to Ritucharya and seasonal living sets out the principle, and the Ayurvedic autumn guide applies it to the months that follow 23 September.
How to observe Ayurveda Day
There is no prescribed observance, which means the day is genuinely useful only if you decide what to do with it. Three approaches work well.
If you are new to Ayurveda
Spend the day reading rather than buying. Start with our Ayurveda Day overview, then take one concept and follow it properly instead of sampling several. The Dosha model is the usual entry point. Avoid mistaking an online questionnaire for a professional assessment: a short quiz can suggest a direction, and that is all it is designed to do.
If you already have a routine
Use the date as an annual review. Ayurveda gives the daily routine its own name, Dinacharya (the ordered daily routine described in the classical texts), and a routine is far easier to audit once a year than to rebuild from nothing. Ask three questions: what time do I actually rise and sleep, what does the first hour of my day look like, and which habit have I quietly abandoned since the spring? Our guide to Dinacharya, the Ayurvedic daily routine gives a structure to check yourself against.
If you teach, study or practise
A fixed date rewards preparation. A reading group, a short public talk, a clinic open evening or a single well made handout all become repeatable once the date is known in advance. The theme published for the observance gives a useful frame: our note on the Ayurveda Day theme explains it in plain language.
Reading Ayurveda carefully
An education day is also a good moment to be precise about language. Ayurveda is a traditional system of practice with its own vocabulary and its own internal logic. In Europe, what may be said about food supplements and cosmetic products is set by regulation, and traditional use is not a medical claim.
Art of Vedas therefore describes classical preparations in classical terms: what a preparation is traditionally used for in Ayurveda, which qualities the tradition assigns to it, and which classical text it is attributed to. Where a question is a health question, it belongs with a qualified healthcare professional or an experienced Ayurvedic practitioner, not with a website.

Frequently asked questions
When is Ayurveda Day?
Ayurveda Day is observed on 23 September each year, and the date is now fixed, so it no longer has to be checked against a lunar calendar. Earlier observances, from 2016 onwards, fell on Dhanteras and therefore moved between October and November from one year to the next. If you are planning anything around the date, 23 September is the one to put in the diary.
Why was the date moved away from Dhanteras?
The reason was practical rather than doctrinal. Dhanteras is a lunar date, so its position in the Gregorian year changes annually, which made it difficult for universities, professional associations, clinics and public bodies to build a repeatable annual programme. Fixing the observance on 23 September allows all of them to schedule years ahead. Dhanteras itself continues unchanged as a cultural festival, with the same meaning it always had.
What does the autumnal equinox have to do with Ayurveda?
The equinox is the point in the year when daylight and darkness are close to equal, which serves as a plain image of the balance that Ayurveda is organised around. The connection is symbolic rather than technical, and no classical text names the equinox as the date of an observance. It is nonetheless seasonally apt: late September is a real turning point in the European year, and classical Ritucharya gives the change between seasons particular attention.
Does Ayurveda Day apply outside India?
The date is an Indian government designation and has no official standing elsewhere. In practice, schools, associations, clinics and individual readers in many countries use it as a shared educational occasion, which is precisely what a fixed date makes possible. Nobody needs permission to read, teach or host a talk on 23 September, and a great deal of the activity around the date now happens outside India.
Is Ayurveda Day a religious observance?
No. The original Dhanteras association carried cultural and religious resonance, and that association still exists on its own calendar. The fixed date of 23 September was set as a public education date, with no ritual attached and no requirement of belief. Separating the two dates is part of what makes this distinction clear.
How should a complete beginner mark the day?
Read one thing properly rather than several things quickly, and resist the urge to buy anything on the first day. The most useful starting subjects are the Dosha model and Dinacharya, the daily routine, because both explain how the rest of the system fits together. If a specific health question sits behind your interest, raise it with a qualified healthcare professional or an experienced Ayurvedic practitioner.
