Answer

In the Jain calendar, Bhadarvo / Bhadrapad month generally ends on Bhadarvo Vad Amas — the new moon day of that month.

Explanation

The exact English calendar date changes every year because the Jain calendar follows the lunar cycle.

If you mean this year, I would need the specific year and your location/tradition to answer accurately, because Jain calendar dates can vary slightly by region and Panchang.

Takeaway

Bhadva ends on Bhadarvo Vad Amas, and the next month begins after that.
