The hadith: “We are a community that does not read or write; the month is like this and like this…” Does this imply relying on calculation?

Question:
Honorable Shaykh, may Allah grant you success, what is the meaning of the Prophet’s (peace and blessings be upon him) hadith: “We are a community that does not read or write; the month is like this and like this” , meaning twenty-nine or thirty days? And does this imply relying on calculation? It does not imply that the month is sometimes twenty-nine days, with the crescent appearing on the twenty-ninth, and sometimes thirty days, with the crescent appearing on the thirtieth.

Yes
