Period of stay in USA for citizenship

[flyby001]

Hi greetings to all. I have a question. Would appreciate if some one can reply.

 

I understand that one needs to spend a period of 5 years in the USA to apply for citizenship. Me and my wife have got our Green cards in Oct 14 and we were told by our attorney that we can initiate the process of applying for the citizenship sometime in Jun 19, but we will not be considered till be complete the 5 year period.

 

My wife intends to go to India for about 4-5 months next year. Will this period not be counted towards the 5 years?  If such absence needs to be counted towards the 5 year period, what can that maximum duration of the absence be?

 

Thanks
