On Mekor Judaica's website, I see a Sephardic siddur for sale, for the שש תעניות, the six fast days.
I was only aware of 5 fast days:
- Ta'anit Esther
- Tzom Gedaliah
- 10th of Tevet
- 17th of Tammuz
- Tisha B'av
What's the sixth? What does this siddur have that's special for this sixth fast day?
New and complete
Fast of speech
