H1b dropbox appointment on a Sunday in August 2022

Hello guys,
My H1b dropbox appointment is in August 2022, at Chennai office, on a Sunday.
Can anyone please confirm if the Sunday appointments are being honored?
My drop-off time is 2:30pm on Sunday.
I am concerned because all websites are showing working hours at drop-off locations from Monday-Friday 10am to 4pm.
If that is the case, why was I allowed to book a Sunday appointment?
I am very concerned before booking my tickets to travel to India.
Can anyone with a similar appointment who was able to successfully submit documents at Pune office. please let me know about your experience?

Looking for help and information.

Kind Regards,

Why dont just call VFS and confirm. If the system let book the appointment you should be good.
