When was Elrond created?

Could you please enlighten me on the genesis of Elrond? I'm quite fascinated by its inception and am eager to know the timeline surrounding its creation. Could you provide me with a specific date or era when Elrond first emerged? It would be immensely helpful if you could also elaborate on the circumstances surrounding its birth, as well as any significant events that preceded or followed its creation. Thank you in advance for your assistance in this matter.
