QUESTION

Baltimore, MD

We have been davening Shabbat afternoon with the Plag HaMinchah split (Mincha before Plag and Ma’ariv after Plag), as we are davening outside in an unlit backyard. Scheduling hakafot for that early feels wrong — when davening Ma’ariv for the next day (whether it’s Yom Tov or chol), everyone then walks home and continues to act like Shabbat until Tzeit HaKokhavim. But to dance hakafot and publicly celebrate the next day of Yom Tov while it is still Shabbat feels different. Am I right in thinking that there might be halakhic issues
