When to recitekodesh l'kodesh at the end of havdalah?

Answer 1

*Your answer is in number 3 below.

1. Going from Shabbat to a normal weeknight we say the normal havdalah, "...Hamavdil bein kodesh l'chol." You can find it in a siddur.

2. Going from Shabbat to chol-hamoed we say the normal havdalah, exactly the same as above.

3. Going from Shabbat to Yom Tov (i.e. when Yom Tov begins Saturday night), havdalah is included in the Yom Tov kiddush. This is the one that concludes with "...Hamavdil bein kodesh l'kodesh." It's different from the normal one in other ways too. Check festival eve kiddush in a siddur. (Found 2 and 3 out at yeshiva.org.il - answered by Rabbi Jonathan Blass)

4. Going from Yom Tov to Shabbat (i.e. when Yom Tov ends on Friday night), there is no havdalah at all. Havdalah is only made when entering a day of lesser holiness, and the Shabbat is holier than all the holidays.

5. When Shabbat and Yom Tov end simultaneously, we say the normal havdalah. (Found 4 and 5 on askmoses.com - answered by Rabbi Naftali Silberberg)

6. Going from Yom Tov to chol-hamoed we say an abridged version of the normal havdalah. We omit the introductory verses which start with "Hinei...", and also omit the spices, and candle. Instead we start with the blessing on the wine, and then go straight to the final paragraph which conlcudes with "...Hamavdil bein kodesh l'chol."
