CarolOklaNola say: Whenever you want it to end, since you haven't given us a time When when the galactic or cosmic year started.. 1.11 galactic years ago the Paleozoic era was ending with with the Permian Triassic extinction event and the Mesozoic era was starting..
You or we determine when the galactic year starts. The Universe or God does NOT.The Universe and Sun does not care.
"...2 galactic years ago The first brain structure appeared in worms
1.11 galactic year ago Permian–Triassic extinction event
0.2935 galactic years ago Cretaceous–Paleogene extinction event
0.001 galactic years ago Appearance of modern humans..."

I am trying to measure it

Zardoz say: It completes an orbit tomorrow afternoon and we start a new orbit on Tuesday.

Hermit Homeboy say: Let's say the period starts right now. This is what your question lacks. A reference point of t=0. The time left is 250 million years. And that's all you need to know.

Stan say: We may have just completed 1 more Orbit yesterday. :)

quantumclaustrophobe say: The sun's about 5 billion years old.
5,000,000,000 / 250,000,000 = 20
So, we've made about 20 laps since the sun was born.
