The Meaning of 12, 21, and 1221

Question:
I just found out recently (for astrology purposes) that my time of birth was 12:21pm on the 21st of [birth month and year removed]. I know very little about astrology or numerology but, having experienced synchronicities and recurring angel numbers on a daily basis for the past year and a half, the symmetry of these numbers struck me immediately as being significant in some way. I'm wondering if someone with a better understanding of numerology can tell me anything interesting about these numbers. Thanks in advance!
