Matthew 24:27 talks about the coming of Jesus Christ, verse 32-34 talks about the generation will live to see the coming of Jesus Christ if they live to see the fig tree budding. That fig tree budding is referring to the time when the Jews return to the land of Israel.
According to Jeremiah 24:5-6, now that generation could refer to somewhere between 70 to 80 years according to Psalm 90:10.
Also, it’s interesting that Matthew 24:32 talks about the timing is when the fig tree starts to bud, so it could be at March, spring to summer.
However, it’s important to understand that we don’t know how long a generation is in the Bible.
And also the Bible says in 1 Thessalonians 5: 1-2, we only know the time and season, and Matthew 24:36 says that we do not know the exact day or hour of the rapture.
