As a boy growing up in an urban industrial town in a middle class family in mid-70s to mid-80s with most of our neighbours friends acquaintances and relatives hailing from more or less same economic group, I found celebration of birthdays as a very simple matter. Generally a small offering might be given in a local temple coupled with preparation of few special delicacies including the mandatory 'Payesh". At the most, an invitation to very close family friends and relatives, if they live in close proximity.
