While filing GSTR-3-B for the month of December 2019 whether we should refer to GSTR-2-A before filing GSTR-3-B and it is also advisable to me as on which date for the month of December 2019 we should file GSTR-3-B

Yes you are right. you should file GSTR3B after taking into account GSTR2A However it is not clear as to what is the timeline to refer GSTR2A (E.G. should we take a cutoff of 10th and then download the 2A and refer or should we download on the month end and refer it) You should file GSTR3B monthly after 10th before 20th of Jan and for quarterly after 10th but before 31st Jan. It is fairly logical to file it after 10 because the government has given time to file GSTR1 for monthly users before the 10th of next month
