No principal canon de Star Wars (os 6 filmes, a série de TV Clone Wars e o filme, a TV Rebels série) não há menções especiais de aniversários sendo comemorados, embora seja bastante claro que as famílias reconhecem.
No " Dia do Império 'Episódio de Rebeldes, é notado que o aniversário de Ezra é no mesmo dia que o homônimo do Dia do Império. Basta dizer que é um pouco deprimente.
Além disso, como apontou @DustinJackson em sua resposta, a ocasião de um Padawan atingir a idade de 13 anos é supostamente celebrada com um pequena cerimônia e marcada por um presente. Embora isso não seja mencionado nos principais shows da Canon, ele recebe uma breve menção na Enciclopédia Star Wars.
Descendo a escala do cânone, há numerosas menções de celebrações de aniversários nos vários romances e quadrinhos da UE.
“You think the war will be over by then?” “If it’s not, we’ll still have a party. All of us.”Uncle Han and Aunt Leia, too?

Qui-Gon felt slightly relieved. At least there was an explanation for the easy entrance.
Lena adjusted one of the holoscreens until it showed a large dining room filled with people.
“It’s Bard’s birthday,” Lena said with relief. A large Fregan birth celebration banner lay across the dining table. “I should have remembered.”
The crowd milled about the room, smiling and carrying glasses filled with red liquid. At first glance it looked like any other party. Qui-Gon looked harder.

She recognized it immediately: The Spring Symphony by celebrated Naboo composer Tofli Argala. She’d mentioned once, in passing, that Argala was her favorite of all Naboo’s music makers. Trust Bail to remember. He knew she’d been homesick of late, having to miss little Pooja’s birthday celebrations again. Of course she’d sent a gift and commed on the day, but a holographic aunt wasn’t the same. Pooja deserved better.
“He had graduated from the Academy and was assigned to a Star Destroyer-the Accuser. On the occasion of his birthday-something most TIE pilots celebrate because of their rarity-he was engaged in a realtime HoloNet connection to our home.
