How can I check my birthday time?

MissNine

I got some months ago a birth report, in which is written that I was born at 15.50.
I have been studing astrology and readng on astrology blogs, and in many is said, that before making a natal chart, in order to get accurate information, is needed to check if the birth time is real or not.
I have found several methods on the net, but I have found them extremly difficult for me, I can not use them, I still know very little astrology to do this.
So my question is if it's really a need that must be done, and in this case, if you can tell me any simple method to try.
Thanks.

Your mom can most likely vouch for the time, as she was most likely there. ;-)

I would also ask the parents for your birth certificate. If you're in the U.S., then you can order a copy of your birth certificate at the county recorder's office. You should have one handy anyway, as you'll need it throughout your life for various reasons.
