"12.23.95" is a song by Jimmy Eat World, released on their album "Clarity" in 1999. The song is not specifically about Christmas, although it mentions the phrase "Merry Christmas, baby" multiple times. The lyrics are open to interpretation, but here's one possible explanation: The song is about regret and the aftermath of a breakup or a strained relationship. The narrator expresses their remorse for leaving someone hanging and alone, and confesses that they didn't know what to say at the time. The repetition of "Merry Christmas, baby" could represent the timing of the events, suggesting that the relationship or the incident in question occurred around Christmas time. The holiday season often amplifies emotions, adding to the weight of the regret and longing expressed in the song. Overall, the song explores themes of communication breakdown, missed opportunities, and the struggle to find the right words to express oneself in a relationship. It captures the sadness and longing that can be felt during the holiday season when one is missing or longing for a loved one. However, it's important to note that interpretations may vary, and the true meaning of the song can be subjective to individual experiences and perspectives.
