Birchas Hachama is said once every 28 years. According to Wikipedia it is said when the sun has returned to ts original position when the world was created.

Jewish tradition says that when the Sun completes this cycle, it has returned to its position when the world was created.

According to the Rabbi Dovid Heber from the Star-K in the footnotes number 11 this is based on the opinion of Rebbi Yehoshua that the world was created in Nissan.

As far as I know and from the answer here the accepted month of the creation of the world is Tishrei.

I have not found anyone suggesting that we should say Birchas Hachama in Tishrei. Why?

The dispute you quote regarding when the world was created is that of R’ Eliezer and R’ Yehoshua, in Rosh HaShanah 10b-12a. At the end of that discussion, the Gemara sticks in this Braisa. Translation is mine; the brackets are from Rashi.

ת"ר חכמי ישראל מונין למבול כר"א ולתקופה כר' יהושע חכמי אומות העולם מונין אף למבול כר' יהושע:

The Sages taught in a Braisa: The Jewish scholars count [years from] the Flood [and Creation, etc.] according to R’ Eliezer [who holds that the world was created in Tishrei], and they count the [solar and lunar] cycles according to R’ Yehoshua [who holds that the world was created in Nissan]. The non-Jewish scholars count even [the years from] the Flood [etc.] according to R’ Yehoshua.

Rashi (end of DH Chachmei Yisrael) explains this dichotomy:

ולא משום דסבירא להו בתשרי נברא העולם אלא דתשרי ראש השנה לשנים ובניסן נברא העולם כדקתני:

Not because they hold that the world was created in Tishrei, but rather that Tishrei is the Rosh HaShanah for years [and therefore we count years from Tishrei], and in Nissan the world was created [and therefore we count the solar and lunar cycles from Nissan].

  • Whose interpretations are in the parentheses - that's not what's written in the Gemmorah?

  • “Translation is mine; the brackets are from Rashi.” I’m paraphrasing Rashi, of course, but if you read him inside, it’s all there.
