יא ר"ש אומר אף ששה עשר לפני החג מעברין היינו תנא קמא
11 — The difficulty remained unsolved. The Master has said: 'R. Judah said: Two thirds of the month. And how much is that? Twenty days. R. Jose ruled: It is to be calculated [thus: if there are] sixteen [days short of completing the <i>Tekufah</i>] which precedes Passover, the year is to be intercalated.'<span class="x" onmousemove="('comment',' In that the end of the cycle is delayed until the 21st of Tishri. V. n. 2. ');"><sup>21</sup></span> But is not this view identical with R. Judah's?<span class="x" onmousemove="('comment',' As it appears that both require the inclusion of only part of the Festival of Ingathering.

Judah, that day completes the previous Tekufah, consequently, if twenty days have passed and the sun has reached its new cycle on the 21st, the new Tekufah begins on the 22nd, in which case not even part of the Feast of Ingathering is included; whilst according to R. Jose's calculation, even if the solstice occurs on the 21st day, that day is added to the new cycle. ');"><sup>23</sup></span> The Master has said: '[R. Jose holds that] if there are sixteen [days short of completing the <i>Tekufah</i>] which precedes the Feast [of Tabernacles], the year is not intercalated.' According to R. Jose, then, only if there are sixteen [days short of completing the <i>Tekufah</i>] preceding the Feast [of Tabernacles is intercalation] not [permitted]; but if there are seventeen or eighteen [days short], the year is intercalated. But has he not himself said: If there are sixteen [days short of completing the <i>Tekufah</i>] which precedes Passover, we may intercalate, but not if less?<span class="x" onmousemove="('comment',' According to the above, in the case of fewer days, if these carry the Tekufah seventeen or eighteen days into Tishri, intercalation is permissible.

But seeing that he spoke of the number sixteen [with regard to the <i>Tekufah</i>] preceding Passover,<span class="x" onmousemove="('comment',' In which case, it is only a shortage of sixteen days which justifies intercalation.

Simeon maintained:<span class="x" onmousemove="('comment',' In contradistinction to R. Jose. ');"><sup>27</sup></span> Even where there are sixteen [days short of completing the <i>Tekufah</i>] which precedes the Feast [of Tabernacles], the year is intercalated.' But is not this view the same as that of the first Tanna?
