It is argued that Yahuah indicated a special-looking moon to Moseh. Something that can easily be recognized as that particular new moon. So, the argument goes that the ‘flat bowl moon’ is such a moon. The two horns are equal in height to each other, the horn on the left to the horn on the right. That is the rim of the bowl and the bowl forming perfectly below.

Indeed, if such a moon were visible in spring, that could signify the new year. Even if it is twice a year, one in spring and one in autumn. (As we know the beginning of the year is in Spring.) And if it is not visible at all locations over the world because of the point of observation that differ at this time, but it is in Jerusalem, the argument would still be valid, in that we have then had to look at Jerusalem. (Yasharel) Then it could be observed from other latitudes over the earth on the same latitude. But it HAS to be visible in Jerusalem to hold true.
