Hobbits and presents

[Ardamir the Blessed]

I believe that only Hobbits of the Shire had the custom of giving away presents on their birthdays:

LR, The Prologue:

As for the Hobbits of the Shire, with whom these tales are concerned, in the days of their peace and prosperity they were a merry folk. They dressed in bright colours, being notably fond of yellow and green; but they seldom wore shoes, since their feet had tough leathery soles and were clad in a thick curling hair, much like the hair of their heads, which was commonly brown. Thus, the only craft little practised among them was shoe-making; but they had long and skilful fingers and could make many other useful and comely things. Their faces were as a rule good-natured rather than beautiful, broad, bright-eyed, red-cheeked, with mouths apt to laughter, and to eating and drinking. And laugh they did, and eat, and drink, often and heartily, being fond of simple jests at all times, and of six meals a day (when they could get them). They were hospitable and delighted in parties, and in presents, which they gave away freely and eagerly accepted.
