Will the Redemption be in Nissan or Tishrei?
There is a dispute in the gemora between Rabbi Eliezer and Rabbi Yehoshua (Rosh Hashana 11a). They disagree on the following point: will the final redemption take place in Tishrei or Nissan. Rabbi Eliezer says that we were redeemed from Egypt in Nissan, but the final redemption will take place in Tishrei. Rabbi Yehoshua says that just as we were redeemed from Egypt in Nissan, so too the final redemption take place in Nissan.
This dispute echoes another dispute between these same two sages: when was the world created? On that question, Rabbi Eliezer says Tishrei (as above) and Rabbi Yehoshua says Nissan (as above).
