The Karthika Masam start date in 2026 falls almost a month later than most Telugu families expect. The sacred month does not begin in October this year. It runs from Tuesday, 10 November 2026 to Tuesday, 8 December 2026 in Andhra Pradesh.
The Hindu calendar added an extra month in mid-2026, so everything shifted. Several popular websites still show October dates copied from last year. Devotees who trust them will light the first deepam nearly four weeks too early.

Karthika Masam Start Date and End Date in 2026
The Karthika Masam start date in Andhra Pradesh is Tuesday, 10 November 2026, and the end date is Tuesday, 8 December 2026. The month opens on Karthika Shuddha Padyami, the first day after the Deepavali new moon. It closes on Karthika Amavasya, twenty-nine days later.
Deepavali itself falls on Sunday, 8 November 2026. Many people therefore assume the sacred month starts on 9 November. However, the Amavasya tithi stretches past sunrise on 9 November. Padyami therefore begins only the following morning.
| Occasion | Date in 2026 | Day |
|---|---|---|
| Deepavali (Ashwayuja Amavasya) | 8 November 2026 | Sunday |
| Karthika Masam begins (Shuddha Padyami) | 10 November 2026 | Tuesday |
| Karthika Pournami | 24 November 2026 | Tuesday |
| Karthika Masam ends (Karthika Amavasya) | 8 December 2026 | Tuesday |
Why the Karthika Masam Start Date Shifted a Month Later
The reason is Adhika Masam. In 2026 the Telugu calendar carried an extra lunar month called Adhika Jyeshta Masam. It ran from 17 May to 15 June 2026. Because panchangam scholars inserted that month, every later lunar month moved roughly thirty days ahead.
A lunar year runs about 354 days, while the solar year runs about 365. That gap of eleven days builds up quietly. So once every 32 to 33 months, the calendar gains a full extra month. Any lunar month with no solar transit, or sankranti, becomes the Adhika month.
The practical effect is easy to see. Karthika Masam ran from 22 October to 20 November in 2025. So the Karthika Masam start date sits almost three weeks later this year. That is why the final day slips into December.
Wrong Karthika Masam Start Date Claims Circulating Online
This is where most competing pages fail. Many websites simply advance last year’s pattern by a few days. They then publish October dates that do not exist in the 2026 panchangam. We checked the pages ranking today, and the wrong Karthika Masam start date claims follow a clear pattern.
- “17 October to 15 November” — roughly where Karthika would have fallen without an Adhika Masam.
- “23 October to 21 November” — last year’s window nudged forward by a day or two.
- “Mid-October to mid-November” — a vague carry-forward with no tithi behind it.
- “8 November to 6 December” — close, though it starts on Deepavali itself instead of Padyami.
- “Somavaram on 8 December” — that date is a Tuesday, and it is Amavasya, not a Monday.
Before you plan a vratam, check that your source names the tithi and the weekday together. A page giving only a bare date, with no Padyami or Amavasya reference, has usually copied it.
How the Telugu Calendar Fixes the Karthika Masam Start Date
Andhra Pradesh follows the Amanta system, where every lunar month ends on Amavasya. Karthika is the eighth month. The Karthika Masam start date always lands the morning after the Deepavali new moon ends. That single rule explains why the English dates move every year.
Karnataka and Maharashtra use the same reckoning, so their dates match Andhra Pradesh exactly. Tamil Nadu and Kerala follow solar calendars instead. Karthigai and Vrischikam therefore do not line up with the Telugu month.
Amanta and Purnimanta: Two Different Start Dates
North India follows the Purnimanta system, where the month ends on the full moon. Kartik there begins in late October 2026 and ends on 24 November 2026. That is the very day Andhra Pradesh observes as Karthika Pournami, the midpoint of its own month.
Both traditions are correct within their own reckoning. Confusion creeps in when a national website prints North Indian dates under a Telugu heading. So if a relative in Delhi says Kartik ended in November, neither of you is wrong. Each system simply sets its own Karthika Masam start date.
| System | Followed in | Karthika 2026 window |
|---|---|---|
| Amanta (new moon to new moon) | Andhra Pradesh, Telangana, Karnataka | 10 November – 8 December |
| Purnimanta (full moon to full moon) | Uttar Pradesh, Bihar, Rajasthan | Late October – 24 November |
Karthika Somavaram Dates in 2026
Karthika Somavaram falls on every Monday inside the month. This year gives devotees four of them: 16 November, 23 November, 30 November and 7 December. Devotees dedicate each Monday to Lord Shiva. Families observe a day-long fast, offer abhishekam, then break the vratam after sunset.
There is a trap here worth knowing. Monday, 9 November 2026 sits between Deepavali and the Karthika Masam start date. It is therefore not a Karthika Somavaram, although several calendars list it as one. The first genuine Somavaram arrives a week later, on 16 November.
- First Somavaram — Monday, 16 November 2026
- Second Somavaram — Monday, 23 November 2026
- Third Somavaram — Monday, 30 November 2026
- Fourth Somavaram — Monday, 7 December 2026
How Many Days Does the Month Run in 2026?
Karthika Masam runs twenty-nine days in 2026, from 10 November to 8 December inclusive. Lunar months last either twenty-nine or thirty days, depending on how the tithis fall. So the exact count changes slightly from year to year.
That length matters if you are observing the full deepa daanam. You will light a lamp on twenty-nine evenings, finishing on Amavasya night. Families planning Vanabhojanalu, the Karthika forest picnic, usually pick a Sunday inside the window. This year that gives four choices: 15, 22, 29 November and 6 December.
Key Days Inside the Month
Karthika Pournami on Tuesday, 24 November 2026 is the spiritual peak of the month. Families light rows of deepams at temple tanks that evening. In many villages, women float lamps in banana-stem boats on the Godavari and the Krishna.
Utthana Ekadashi falls on Friday, 20 November 2026, when Lord Vishnu wakes from the four-month Chaturmasya rest. Ksheerabdi Dwadashi and Tulasi Kalyanam follow the next day, on Saturday, 21 November. For the full month of poojas and vratams, see our Karthika Masam festival and pooja dates guide. We also cover Tulsi Vivah tithi and muhurtham separately.
One regional detail confuses many readers. The Tamil Karthigai Deepam at Tiruvannamalai follows the Krittika nakshatra and falls in early December 2026. It therefore does not share a date with the Andhra Karthika Deepam on Pournami. Confirm the Tiruvannamalai date on the temple’s own announcement closer to the day.
Planning Temple Visits Once Karthika Masam Begins
Shiva temples across Andhra Pradesh fill up sharply during this month. Srisailam, Draksharama, Kotipalli and Amaravati draw their heaviest crowds on the four Somavarams and on Pournami. Since the Karthika Masam start date is later than usual, Pournami lands on a Tuesday working day rather than a weekend.
Plan around three realities that official notices rarely mention. Abhishekam tickets at major Shiva kshetras often sell out by mid-morning on Somavarams. River ghats at Kotipalli and Bhadrachalam get congested before sunrise for Karthika snanam. Temples also extend Pournami timings, but they announce the change only days ahead.
If Somavaram slots run out, three fallbacks work well. Book a weekday abhishekam earlier in the same week. Try a smaller local Shiva temple, where the queue moves faster. Otherwise wait for the following Monday.
Where a seva carries a fixed quota, no alternative exists for that date. In that case, simply plan for the next Somavaram. Check timings on the Andhra Pradesh Endowments Department portal, the Srisaila Devasthanam site, or Tirumala Tirupati Devasthanams (TTD).
A Note on Snanam and Fasting
Karthika snanam means a cold-water bath before sunrise. This year the month falls in the coldest weeks of the year. River water in late November can be genuinely harsh at 4 am.
Elderly devotees, children, and anyone with heart or blood-pressure conditions should bathe at home with warm water instead. Tradition fully permits this.
Fasting practices vary too. Ekabhuktam means one meal a day, while naktha vratam means eating only after sunset. If you are pregnant, diabetic, or on regular medication, please speak to your doctor first.
These observances are matters of faith and Vedic tradition. They are not a substitute for medical treatment.
Mistakes Devotees Make With These Dates
The most common error is starting the vratam on Deepavali night. The month actually begins the morning after Amavasya ends. So the first deepam belongs to 10 November, not 8 or 9 November.
A second mistake is counting Somavarams from the wrong end. Devotees sometimes include the Monday just before Padyami. They then stop a week early and miss the fourth Somavaram on 7 December.
The third is trusting a printed calendar from an earlier year. Because of the Adhika Masam, a 2025 wall calendar misses the Karthika Masam start date by nearly three weeks. Cross-check against a current panchangam. Remember that Deepavali and Yama Deepam timings shift with it as well.
Before You Light the First Deepam
The Karthika Masam start date and end date are unusually easy to remember this year. The month runs 10 November to 8 December. Pournami sits exactly at the halfway mark, on 24 November.
Mark the four Somavarams first, since temples and river ghats are busiest then. Work backwards from Pournami if you are planning a family visit or a local deepotsavam.
Above all, ignore any October date you see for this year. The Adhika Jyeshta Masam moved the whole calendar. A page that misses that has not caught up with 2026.
Karthika Masam Start Date: Frequently Asked Questions
What is the Karthika Masam start date in 2026?
The Karthika Masam start date is Tuesday, 10 November 2026 in Andhra Pradesh and Telangana. It falls on Karthika Shuddha Padyami, the first day after Deepavali Amavasya ends. Deepavali itself falls on Sunday, 8 November 2026.
When does Karthika Masam end in 2026?
The month ends on Tuesday, 8 December 2026, on Karthika Amavasya. That gives a full span of twenty-nine days. Margasira Masam then begins the following morning, on 9 December 2026.
Why do some websites show an October Karthika Masam start date?
Those sites carried last year’s October–November pattern forward. They missed Adhika Jyeshta Masam, the extra lunar month that ran from 17 May to 15 June 2026. That insertion pushed every later month roughly thirty days ahead. Any October date is therefore incorrect for this year.
How many Karthika Somavarams are there in 2026?
There are four Karthika Somavarams in 2026: Monday 16 November, Monday 23 November, Monday 30 November and Monday 7 December. Monday 9 November does not count, because the month had not yet begun.
What is the date of Karthika Pournami in 2026?
Karthika Pournami falls on Tuesday, 24 November 2026. It is the full moon day and the most significant day of the month. Devotees light rows of deepams and float lamps on rivers and temple tanks.
Is Karthika Masam the same in Andhra Pradesh and North India?
No, the two follow different systems. Andhra Pradesh uses the Amanta calendar, running 10 November to 8 December 2026. North India uses the Purnimanta calendar, which begins in late October and ends on 24 November 2026.
Can I start Karthika vratam in the middle of the month?
Yes, devotees commonly begin on a Somavaram or on Pournami instead of Padyami. Tradition treats sincerity and consistency as more important than the starting day. Many families simply start on the first Monday, 16 November 2026.
Does the Karthika Masam start date always follow Deepavali?
In the Telugu Amanta calendar, yes. The month always begins after the Deepavali Amavasya tithi ends. The gap can be one or two days, depending on when that tithi closes. In 2026 the gap is two days, since Amavasya continues past sunrise on 9 November.
