Mumbai operates on Indian Standard Time (IST), which is UTC+5:30. I can’t provide the exact current clock time, but you can check your device for the precise moment.

Note: If you meant the Jain observance known as Navkarsi (a vrata observed on certain days), I can share its meaning and how it’s observed according to Digambar/Shwetambar directions. If you’d like that, tell me and I’ll explain simply.
