Amitesh's anniversary in the month which has 30 days but not on the odd numbered date.

Ashok’s anniversary is before Amod's Anniversary it is clear that Ashok and Amod have their anniversary in the month of July where Ashok's anniversary is on 12th July and Amod's anniversary is on 27th July. 
Only one person has his anniversary between Ashwani and Aniket. Aliya doesn't have his anniversary on the even numbered date. Aniket has his anniversary just after Aditya. Hence, Aniketis anniversary is on 27 November and Ashwani's anniversary is on 27th September As Aliya doesn't have his anniversary on even numbered date so Aliya's anniversary is on 27th may. Hence, Aniket and Aditya both have their anniversary in the month of November
