First agm of cooperative housing society

You may visit the bylaws if your association in which you can find all the specifications and procedures and proceed accordingly. 

In the bylaws, there will be a column for General Body meetings and their functions and if you have mentioned the month as noted in the bylaw, you have to conduct the AGM shall be conducted every year  I

You held the first general meeting of your society in 2003. And you have not held any general meeting for more than 20 years after that. That is surely not acceptable. The main purpose of the AGM is to close annual accounts, get it audited and present it to the general meeting for approval. Whatever date that you may have held your first general meeting, at the next 31st of March you must close the accounts and get it audited by the auditor whom the general meeting would have appointed at the first meeting and present the accounts for approval before the general meeting before 30th September of the same year. That general meeting is called the AGM. Thereafter on every 31st of March you must close the accounts, get it audited and present it to the AGM.

I am sorry. There was a typo mistake in my question. First AGM was held on 16/12/2023 and not 2003. Sorry for the confusion.
