Parshvanath ke janm din ko Poṣh‑daśamī (Posh Dashami) isliye kaha jata hai kyunki:

• Naam ka arth: Poṣa (Posh) mahine ki dasvi tithi (das) ke din Parshvanath ji ki janm kalyanaka manaya jata hai. Isliye is din ko Poṣhī‑daśamī ya Posh Dasham kaha jata hai.
• Calendar par adharit: North Indian calendar mein Poṣa mahine ki Krishna/antras dharma ke hisaab se 9th, 10th, ya 11th din aata hai, jabki Gujarati calendar jaise regional calendars mein tithi thodi alag hoti hai. Par mool arth wahi hai ki Parshvanath ki janm kalyanaka Poṣa mahasya dasvi tithi par manaya jata hai. ( jainknowledge.com)
• Ritirivaj ki roopantar: Alag-alag kshetron ki panchang calculation ke chalte exact date har saal alag ho sakti hai, lekin tattva Poṣa Dashami hi hai jo Parshvanath ki janm kalyanaka ko darshata hai. ( jainknowledge.com)

Mula arth ko yaad rakhen to: Poṣa (mahina) ki dasvi tithi par Parshvanath ka janm yaad kiya jata hai; isliye is din ko Poṣh‑daśamī ya Posh Dashami kehte hain.

Aap chahein to apne shehar/mandir ke panchang ke hisaab se exact Gregorian tareekh dekh sakte hain; 2025 ke liye ya aage ke saal ke liye regional calendar dekhna uchit hota hai. ( jainknowledge.com)
