My understanding is that this is how it works. When you are younger, everything is novel, and therefore your brain is making and timestamping more memories. We therefore have a high resolution timescale of memories. As we age, we have less and less novelty. We learn less, have fewer first time experiences. Therefore, we lose resolution to our timescale as weeks, months, and for some, even years blend together.
