This weekend, with Shavuot starting motsei Shabbat, we face the reverse of the situation we faced when Seventh Day Pesach was Friday 6 weeks ago. There is no need for an Eruv Tavshilin as there was then, but there are other points to pay attention to:
- Cooking is permitted on Hag if begun from an existing flame. The way to do this is light a yarzheit candle before Shabbat. It will still be burning when Shabbat is over, so you will have a fire from which to light the candles for Hag and to cook. You may want to light a second yarzheit candle motsei Shabbat so you will have an existing fire all Hag (Sunday).
- In the Amidah for motzei Shabbat/Maariv yom tov there is a havadalah paragraph in the 4th bracha (v’todi’einu) for moving between Shabbat and Yom Tov (Sim Shalom, p. 306).
- Kiddush on Motzei Shabbat is known as YaKaNaHaZ – Yayin (wine), Kiddush, Ner (candle – borei me’orei ha’eish), Havdalah, Zman (Shehehianu). This can be found on the page with Yom Tov Kiddush (pp 742-745 in Sim Shalom, note top of 744).
- You may add water to the Shabbat dud mayim after Shabbat. It need not be hot or boiling. BE CAREFUL!!
- Havdalah at the end of Hag, Sunday night, is regular Hag Havdalah, NO spices or candle.
Hope this is helpful. Hag Shavuot Sameach!
