104 weeks is exactly two years — 2 × 52. It's the cleanest weeks-to-years conversion there is, which is why contracts, leases, and warranties so often come in 104-week (two-year) terms. Counting leap days it's a hair under, about 1 year and 12 months, but for any practical purpose 104 weeks is two years on the nose.
The straight answer
104 weeks ÷ 52 = 2 years. Counting the extra leap days (52.18 weeks per year), the more precise figure is 2.0 years — about 2 years. For most purposes the round 2.0 years is the number you want.

A span you can actually count
The reason it's worth converting 104 weeks into years is that the two numbers feel completely different. "2.0 years" sounds like a vague block of time. "104 weeks" sounds like something you could tick off on a wall, because you almost could.
At one weekend per week, 104 weeks is also about 104 weekends — the unit a short span is really lived in. Whether that feels like a lot or a little depends mostly on what you're measuring against.
