Jewish Festivals: Candles: Lighting with Delay until Sunset

As on Shabbat, you may say “I am lighting Jewish festival candles but not starting the Jewish festival until sunset” to delay observing the Jewish festival until sunset, but this in only b'diavad.
Note As for Shabbat, women should not routinely start Jewish festivals at sunset since the proper time for women to begin Jewish festivals is at candle lighting (typically 18 minutes before sunset).
