Lahiri Ayanamsa Value 2026: Exact Degrees Table for Vedic Astrology (2000–2035)

The Lahiri (Chitra Paksha) ayanamsa on January 1, 2026 is approximately **24°07′47″** according to the Swiss Ephemeris implementation used in Jagannatha Hora.

The current Lahiri ayanamsa value in 2026 is approximately 24°07′. This is the official ayanamsa used in Vedic astrology and is the value implemented in Jagannatha Hora and the Swiss Ephemeris. For precision work such as birth time rectification or KP sub-lord analysis, confirm the exact value for the specific date directly in Jagannatha Hora.

Current Ayanamsa Value Today

The Lahiri ayanamsa increases slightly every day as Earth’s rotational axis slowly shifts relative to the fixed stars. In 2026 the value lies in the 24°07′ to 24°08′ range. No static table can give you today’s precise value to the arc-second.

For the exact value on today’s date: open Jagannatha Hora, go to Utilities, select Transits / Gochar, enter today’s date, and read the ayanamsa displayed in the panel header. That figure is the canonical value for your current chart work. The JHora transit guide covers the full process step by step.

Quick Reference: Lahiri Ayanamsa Values for Early 2026

Values correspond to the Lahiri ayanamsa as implemented in Swiss Ephemeris and Jagannatha Hora. Verify in JHora for arc-second precision before muhurat selection or birth time rectification.

Monthly Lahiri Ayanamsa Values for 2026

The monthly increase is approximately 3 to 4 arc-seconds. For most natal chart work, the difference between January and December within a single year does not affect sign placements or sub-lord assignments. It becomes relevant only when a planet sits within a few arc-seconds of a nakshatra sub-boundary on the exact date of birth.

Lahiri Ayanamsa Values by Year (2000–2035)

Values correspond approximately to January 1 of each year using the Lahiri ayanamsa as implemented in Swiss Ephemeris and Jagannatha Hora. Values from 2027 onward are extrapolated using the approximate 50″ yearly increase and carry increasing uncertainty. Verify in Jagannatha Hora before applying to precision work.

* Values from 2027 onward are linear extrapolations from the 2026 base. Verify in JHora before using in consultations.

What Is the Ayanamsa

The ayanamsa is the angular difference between the tropical zodiac used in Western astrology and the sidereal zodiac used in Vedic astrology.

The tropical zodiac is tied to the seasons. It fixes 0° Aries at the vernal equinox, the point where the Sun crosses the celestial equator moving northward each spring. The sidereal zodiac is fixed relative to the actual background stars.

Because Earth’s rotational axis traces a slow circular path over approximately 25,920 years, the vernal equinox drifts backward through the sidereal zodiac. This is the precession of the equinoxes. The ayanamsa measures the accumulated drift at any given moment. Currently that drift is just over 24 degrees, meaning every planet’s tropical longitude is approximately 24° ahead of its sidereal position in the Vedic chart.

How to Convert Tropical Positions to Sidereal

Subtract the ayanamsa from the tropical longitude. Example using the January 2026 value:

Tropical position: 15° 00′ 00″ Pisces (= 345° 00′ 00″)
Ayanamsa: 24° 07′ 47″
Sidereal result: 345° 00′ 00″ − 24° 07′ 47″ = 320° 52′ 13″ = 20° 52′ 13″ Aquarius

Jagannatha Hora performs this subtraction automatically when casting any chart. The conversion step is only needed manually when importing planetary positions from a tropical source.

Why Lahiri Is the Official Indian Ayanamsa

The Lahiri ayanamsa, formally called the Chitra Paksha ayanamsa, was adopted as the national standard by the Government of India in 1956 following the recommendations of the Calendar Reform Committee chaired by physicist Dr. Meghnad Saha. The reference point is the star Chitra (Spica, alpha Virginis), fixed at exactly 0° Libra in the sidereal zodiac.

The epoch at which the tropical and sidereal zodiacs coincided is calculated at approximately 285 AD using this reference. The Lahiri function is implemented in the Indian Astronomical Ephemeris published by the Positional Astronomy Centre, Kolkata, in Swiss Ephemeris, and in Jagannatha Hora. It is the reference standard for official Panchang calculations across India.

Rate of Change: How the Ayanamsa Increases

The ayanamsa increases at approximately 50 arc-seconds per year, reflecting the current rate of axial precession. This rate is not perfectly constant — it varies slightly due to gravitational influences from the Moon and planets — which is why the Swiss Ephemeris applies non-linear corrections rather than simple linear extrapolation.

In practical terms:

• Per year: approximately 50″
• Per month: approximately 3 to 4″
• Per day: approximately 0.14″

For standard natal chart work, using the January 1 value for the birth year introduces at most a few arc-seconds of error for births later in that year. This does not affect sign placements or sub-lord assignments in the vast majority of cases. The exception is birth time rectification, where arc-second precision matters and the ayanamsa must be read for the exact birth date and time. Jagannatha Hora handles this automatically.

KP Ayanamsa vs. Lahiri Ayanamsa

Three ayanamsa values are associated with Krishnamurti Paddhati practice. Understanding the difference is important for anyone managing a chart archive or verifying published KP analyses.

The KP Old ayanamsa tables published in K.S. Krishnamurti’s original texts contained a systematic error of approximately 6 arc-minutes below the correct Lahiri value. A 6-minute offset is significant in KP work because planets near nakshatra boundaries shift star lords, which changes their house significations in the sub-lord framework. KP New corrects this error. The difference between KP New and Lahiri, at approximately 5 arc-seconds, is negligible in routine chart work.

A full comparison of KP and Vedic frameworks is at the KP vs Vedic astrology guide.

How to Verify the Ayanamsa in Jagannatha Hora

Step 1: Confirm the Active Ayanamsa

Open Jagannatha Hora. Go to Settings in the top menu bar and select Ayanamsa. The active system has a checkmark. Confirm it reads Lahiri (Chitra Paksha). If not, click it to activate it.

Step 2: Open the Transits Panel

Go to Utilities in the top menu and select Transits / Gochar.

Step 3: Enter the Date

Enter the date you want to check. The ayanamsa value for that date appears in the panel header in degrees, minutes, and seconds. This is the canonical value under the active ayanamsa setting.

Step 4: Checking an Imported Chart

The ayanamsa used for any chart is visible in JHora’s chart header panel. If it does not match your working standard, go to Settings, switch to Lahiri, and recalculate. Two charts of the same birth data cast under different ayanamsas are not interchangeable in KP sub-lord analysis.

Conclusion

The Lahiri (Chitra Paksha) ayanamsa is the standard reference for Vedic and KP astrology. In 2026 the value lies in the 24°07′ to 24°08′ range and increases gradually throughout the year. The January 1, 2026 value is 24° 07′ 47″.For any precision work — muhurat selection, birth time rectification, or KP horary — confirm the exact value in Jagannatha Hora rather than relying on any static table. Practitioners new to the KP framework will find the KP astrology introduction a useful starting point before working with the ayanamsa settings.
