Two ways to name a lunar month
Hindu timekeeping is lunisolar — months follow the Moon, years align with seasons through intercalary (adhik) months. But when does “Chaitra month” start? That depends on whether your panchanga uses Amanta or Purnimanta. Both are ancient; neither is “wrong.” Maharashtra households, temples, and Marathi publishers overwhelmingly use Amanta (also called Chandramana in conversation).
Confusion appears when:
- A Delhi newspaper says “Chaitra Navratri” while your Marathi calendar still shows Phalguna.
- Google shows two different dates for the same festival name.
- An NRI child asks why English Wikipedia and Ajji’s Kalnirnay disagree.
This guide untangles naming — not to debate theology, but so you can use marathipanchanga.in confidently alongside family tradition.
Amanta (अमांत) — month ends on Amavasya
In Amanta, a lunar month runs from the day after Amavasya through the next Amavasya. The new month begins on Shukla Pratipada (first bright tithi) immediately following dark moon.
Characteristics:
- Used in Maharashtra, Karnataka, Telangana, Tamil Nadu, Gujarat (with local variants) for festival dates.
- Gudi Padwa = Chaitra Shukla 1 = day after Chaitra Amavasya.
- Month names in Marathi panchanga: Chaitra, Vaishakha, Jyeshtha… ending each at Amavasya.
- Kalnirnay and most Marathi wall calendars are Amanta.
On our site, 18 March 2026 is Chaitra Amavasya and 19 March is Gudi Padwa — classic Amanta pairing. See Gudi Padwa 2026 Guide and March calendar.
Purnimanta (पूर्णिमांत) — month ends on Pournima
In Purnimanta, the month runs from the day after Pournima to the next Pournima. The “first day” of Chaitra in Purnimanta reckoning aligns differently from Amanta labels mid-month.
Characteristics:
- Common in North India — UP, Bihar, Rajasthan, MP — for civil and ritual month naming.
- Festival tithi (e.g. Rama Navami = Navami) is often the same event, but the month name printed on the page header may differ for half a fortnight.
- Government Hindi notifications sometimes follow Purnimanta month vocabulary.
Important: Purnimanta vs Amanta is primarily a month boundary labelling issue. The festival still occurs on a specific tithi — Rama Navami on Navami — but which month banner appears above that tithi shifts.
Side-by-side comparison
| Topic | Amanta (Maharashtra) | Purnimanta (North) |
|---|---|---|
| Month ends on | Amavasya (new moon) | Pournima (full moon) |
| New month starts | Shukla Pratipada after Amavasya | Shukla Pratipada after Pournima (in their count) |
| Gudi Padwa / Ugadi | Chaitra Shukla 1 (Amanta Chaitra day 1) | Same tithi; may read “Chaitra” or still “Phalguna” on banner |
| Typical calendars | Kalnirnay, Marathi panchanga apps | Hindi panchang, many North booklets |
| marathipanchanga.in | Yes — Amanta | Not used for month labels |
Worked example — Gudi Padwa and Chaitra 2026
Timeline around Marathi New Year (Amanta):
- 18 March 2026 — Chaitra Amavasya (last day of Phalguna Amanta month ending).
- 19 March 2026 — Chaitra Shukla Pratipada = Gudi Padwa.
- 26 March 2026 — Rama Navami (Navami tithi).
- 1 April 2026 — Chaitra Pournima on our festivals list.
A Purnimanta calendar user celebrating the same Rama Navami may still call the day “Chaitra Navami” but their calendar header might have labelled the fortnight differently in early March. The English date (26 March) usually matches when tithi aligns — arguments are often about month names, not the day off work.
Why English festival dates still disagree online
Amanta vs Purnimanta is only one factor. Also:
Tithi end time (IST vs US)
Ekadashi in Mumbai may still be previous tithi in California — NRIs must pick an observance convention (local temple vs India date).
Sunrise rule
Festival “day” is often sunrise to sunrise. If tithi starts after sunrise, some traditions shift observance — publishers differ.
Adhik maas (extra month)
In adhik years, festivals shift — 2026 lists on our site follow compiled references; always verify adhik years with priest.
Regional sampradaya
Konkan vs Vidarbha may differ on one vrata day — About explains we use Mumbai-oriented consensus.
Social media graphic dates
Instagram infographics often copy last year’s English date without updating tithi — always cross-check marathipanchanga.in festivals before sharing in family group. A wrong Ekadashi forward hurts someone fasting on the wrong day.
Month names through the year — Amanta view
Walking through 2026 on an Amanta calendar (simplified):
- Paush / Magha — January on English wall; Makar Sankranti, Shivratri.
- Phalguna — Holi, end on Amavasya before Gudi Padwa.
- Chaitra — begins 19 March 2026 (Padwa); Rama Navami, Hanuman Jayanti.
- Vaishakha — Akshaya Tritiya, hot season weddings begin.
- Jyeshtha → Ashadha — Devshayani, start of monsoon pause for some rituals.
- Shravan → Bhadrapada — Ganesh Chaturthi, Raksha Bandhan overlap regionally.
- Ashwin → Kartik — Navaratri, Dasara, Diwali chain.
- Margashirsha → Paush — winter weddings, Mokshada Ekadashi.
Each name ends at its Amavasya in Amanta reckoning — browse month pages for exact 2026 English mapping.
Why marathipanchanga.in uses Amanta
Our audience is Maharashtra and Marathi speakers worldwide. Amanta matches:
- Kalnirnay-style home calendars.
- State school holiday patterns around Gudi Padwa, Ganesh Chaturthi, Diwali Padwa.
- Marathi temple notices and municipal holiday boards in Mumbai.
All month pages (January through December), festivals, and guides like What is Marathi Panchanga? use Amanta Chandramana unless explicitly noted.
If you marry into a North Indian family using Purnimanta labels, compare tithi — you may celebrate the same English date with different month names on two calendars.
Adhik maas (extra month) — when it matters
Approximately every three years an adhik maas (intercalary month) appears to align lunar and solar years. Festival spacing shifts — publishers issue special supplements. If a relative says “this year has two Jyeshtha,” check a full almanac; our 2026 tables follow compiled references without adhik duplication unless noted on festivals.
Digital apps and Amanta
Most Marathi calendar apps default to Amanta; Hindi apps may default Purnimanta — switch setting before comparing Gudi Padwa countdown. marathipanchanga.in has no toggle because our audience is Maharashtra-first.
Case study — Diwali Padwa confusion
Diwali Amavasya and Balipratipada (Padwa) sit at the Kartik month boundary in Amanta. A North Indian relative may say “Kartik Amavasya Diwali” while your Marathi calendar agrees on the English date but showed Ashwin ending at Amavasya the night before. Both households light diyas on the same evening; argument is month naming on the calendar header, not whether to celebrate. When sharing festival rows, cite English date + Marathi name to reduce WhatsApp debate.
Case study — Ganesh Chaturthi
Bhadrapada Shukla Chaturthi is the tithi — Amanta Bhadrapada in Maharashtra. Purnimanta calendars may still print “Bhadrapada” or “Shravana” on the banner depending on publisher cutoff. Lalbaug cha Raja visarjan follows Mumbai police schedule on Anant Chaturdashi tithi, not English weekday alone.
Frequently asked questions
Quick reference card
Print mentally: Amanta = Amavasya ends month. Purnimanta = Pournima ends month. Maharashtra / this site = Amanta. Same tithi festivals often share English date; month label on Hindi TV may differ for ~15 days per cycle. Gudi Padwa 2026 = 19 March. When cousins argue, open festivals table and read tithi row together instead of debating WhatsApp forwards.
Which is more correct?
Both are valid regional systems. Follow your family and local temple.
Does Amanta change Ekadashi dates?
Ekadashi is tithi-based — same Moon day; month label on calendar may differ mid-cycle.
Why does Hindi news say different month?
Often Purnimanta month naming — compare tithi, not only headline.
Gudi Padwa date in both systems?
19 March 2026 for Chaitra Shukla 1 observance on this site.
Where to learn daily limbs?
Will switching to Purnimanta change my Ekadashi date?
Usually not — Ekadashi is tithi-based. Month banner on app may differ; tithi row should match if same publisher logic.
How do I explain this to kids in one sentence?
“Maharashtra calendar month ends on Amavasya; North India often ends month on Pournima — same festivals, different month labels for a few days.” Show them Gudi Padwa on 19 March as a concrete example.
Does Amanta affect Rahu Kaal?
No — Rahu Kaal depends on weekday and sunrise, not lunar month system. See Rahu guide. Month system only affects which Marathi month name appears above a tithi on the calendar header, not the Rahu table clock time. Keep both concepts separate when teaching newcomers to marathipanchanga.in.

Summary: Use Amanta when reading marathipanchanga.in and Marathi wall calendars. When Hindi media uses Purnimanta month names, compare tithi and English date — not headline month alone. Teach children both systems exist to prevent “your calendar is wrong” arguments at joint family festivals. Our month pages through December stay Amanta throughout 2026. When forwarding dates, write “19 Mar — Gudi Padwa (Amanta Chaitra Pratipada)” instead of only “Happy New Year” — precision prevents cousin confusion in mixed Purnimanta-Amanta families spread across India and abroad.
