Simple but very urgent query in VAT

Dear All,

Can you plese tell me Due date for filing of Monthly return In Gujrat ( Form 201, 201 A etc.) for a company dealing in oil say ONGC. I am confused between two options. Is it 22nd or 30th of following month.

In some sources it is 22nd and in some it is 30th. If any body has any known person in Gujrat , can they please let me know...

Will be very very thankful to them..

Regards,
