Vikram Samvat tithis for a whole year city‑wise (like “all Jain tithis for 2026 – Mumbai”) are normally given in a Jain Panchāng or printed wall calendar, not listed sutra‑style in our scriptures. Generating a full, accurate day‑by‑day table here is not practical or reliable.

But I can tell you the basic framework and how to get the exact tithi for any date:

---

1. Which Vikram Samvat year covers 2026?

For Mumbai, India:

• Gregorian year 2026 mostly corresponds to

Vikram Samvat 2082–2083 and Vīr Samvat 2552–2553 (Mahavir Samvat).

• Example around “today”:

23 January 2026 ≈ Māgh Sud 5, Vikram Samvat 2082 (Magh Shukla Panchami).

(Exact start/end of months and when the tithi changes during the day must be taken from a panchāng.)

2. Jain tithi vs general (Hindu) tithi

For practical purposes, the lunar tithi itself is the same (based on the Moon–Sun angle), but:

1. Day boundary:

- In Jain usage, the “tithi of the day” is usually taken from sunrise to next sunrise at the given place (here, Mumbai). - So sometimes what general panchāng calls “today’s tithi” (based on midnight or a different rule) may differ from what Jains treat as the main tithi for that day’s vrats.

1. Festival / vrat usage:

- Jain panchāng will mark Paryushan, Ayambil Oli, Aatham, Chaudas, Kalyānak days, Samvatsari, etc., which are specifically important in Jain Dharma.

Because of these details, Jains rely on a Jain‑specific panchāng rather than a generic Hindu calendar.

3. How to get accurate Jain tithi for 2026 – Mumbai

To know, for example, “On 15 March 2026 in Mumbai, which Jain tithi (Vikram Samvat) is it?” you should use one of these:

1. Printed Jain Calendar / Panchāng (for 2026)

- Example types: “Padmodaya Jain Calendar”, “Jain Tithi Darpan”, “Jain Panchāng” etc. - Make sure it clearly mentions: - Year: Vikram Samvat 2082–2083 - Place: Mumbai (or “Bombay / Metro cities” including Mumbai) - These calendars already adjust for Mumbai sunrise, so the tithi shown for each date will be the Jain tithi for that city.

1. Online Jain Panchāng

- Some Jain panchāng sites let you select city = Bombay/Mumbai and date, and they show: - Jain tithi (e.g., “Māgh Sud 3”) - Vikram Samvat year - Often also mark Jain parvas and Kalyānak days. - Always choose “Bombay / Mumbai” from the city list to avoid time‑zone errors.

Once you have such a panchāng for 2026, you will get a complete list of Jain tithis for every day of 2026 in Mumbai, which is what you are asking for.

4. If you want only some key Jain dates for 2026

If you are mainly interested in things like:

• Paryushan (Śvetāmbara / Digambara)
• Mahavir Jayanti (Chaitra Sud Teras / Chaitra Shukla 13)
• Samvatsari (Kshamāpanā)
• Important Aatham/Chaudas for upvās or ayambil

tell me which specific festivals or months you care about, and I can list their approximate Gregorian dates for 2026 along with the Jain tithi and Vikram Samvat — but not a full 365‑day tithi table.
