In Jain Dharma, “Pakhi” (पाखी / पक्षी) usually means:

• Doing a special vrat (fast / upvas / ayambil / etc.) every 15 days, on a fixed tithi (like every Sud 8, Vad 8, Sud 5, etc.)
• It is based on the lunar Jain calendar (tithis) – not on the English dates.

Because Pakhi depends on:

1. Your chosen vrat type (e.g., Upvas Pakhi, Ayambil Pakhi, Ekasan Pakhi, etc.)
2. Your chosen tithi (e.g., every Sud Ashtami, every Chaudash, etc.)
3. Your Jain calendar / area (desh–kal)

the exact English dates for Pakhi in January 2026 will change according to:

• Which tithi you observe as Pakhi
• Which Jain panchang you follow (different regions sometimes differ by a day)

So, I cannot reliably list the exact Pakhi dates for January 2026 without a specific Jain panchang.

To find correct Pakhi dates for January 2026:

• Take your regular Jain panchang (for your sangh / city) for the year 2026
• Mark the tithi you observe as Pakhi (e.g., every Sud 8 and Vad 8)
• Then match those tithis with Gregorian dates in January 2026

If you tell me:

• Which Pakhi vrat (Upvas / Ayambil / Ekasan / etc.)
• On which tithi you keep it (Sud/Vad and date)
• Your city/country (for panchang difference)

then a local Jain panchang or your Jain sangh can give you the exact January 2026 Pakhi dates accurately.
