In the Diaspora, we will start 7 weeks later - on Motzai Shabbat VaYeshev, the eve of Sunday 6 December.
If you forgot to add "וְתֵן טַל וּמָטָר לִבְרָכָה" - "and bless us with dew and rain", then:
- If you remember before you finish the 9th Bracha - מְבָרֵךְ הַשָּׁנִים - then you insert it and continue from there.
- If you already said "Baruch Ata HaShem" of the 9th Bracha, then you insert it into שְׁמַע קוֹלֵנוּ - the 16th Bracha - before "כִּי אַתָּה שׁוֹמֵעַ ".
- If you forget to say it in שְׁמַע קוֹלֵנוּ then you need to go back to the 9th Bracha - בָּרֵךְ עָלֵינוּ.
- If you didn't remember until you finished the Amida (defined as saying "יִהְיוּ לְרָצוֹן אִמְרֵי פִי ") then you have to restart the entire Amida.
