(TRANSLATION: The Gemara says that the Beis Din would interrogate the witnesses with seven "Chakirot":
1) in which Shemitah cycle the event occurred,
2) in which year it occurred,
3) in which month it occurred, etc.
When the witness answers Beis Din that the event occurred, for example, in the year 5758, has the witness not answered the first question, but only the second? As long as he knows the year, he also knows what Shemitah cycle the event occurred in (he can simply divide the year by the Yovel cycle and then divide that by seven to get which Shemitah cycle that year is). Why, then, does Beis Din ask both these questions?
Interesting question. However, we find in RASHI (Sanhedrin 40a) that the question "which year did the event occur" does not refer to the year from Creation (e.g. 5758), but rather it refers to the year of the Shemitah cycle (that is, is it the first, second, third, ... or seventh year of the cycle). The first question, "which Shemitah cycle did the event occur," refers to the first, second,... or seventh Shemitah series of the Yovel cycle. Thus, he does not have to know the year from Creation in which the event took place, and thus he has no external way of knowing what Shemitah cycle the event occurred in.
Besides, it is not so simple to calculate the Shemitah cycle by dividing the years since Creation, since the Yovel cycles are not counted beginning from the time of Creation, but from the time that Eretz Yisrael was settled.
