As we discussed here about a month ago, *any* public fast that falls on a
Friday (e.g. any of the fasts listed in siman 580, or the chevra kadisha
fast day) must be completed.  What's more, if the first time one fasted on
a yartzeit it wasn't a Friday, then when it does fall on a Friday one must
complete it (unless one anticipated this from the beginning, and made an
explicit tnai otherwise).

Tish'a B'av doesn't have a "b'etzem hayom hazeh".
