This year it shall be difficult to utilize the subtitles or even microphones at the sumptuous Tisha b’Ov celebrations, because we still have to observe Shabbos, even in the midst of Tish b’Ov celebrations.
Then again , Tammuz may commence 1 day earlier after 29 days of Sivon, Al Pi Re’iyoh, considering that all Molados are 1 day early this year, and & then Ov shall commence on Thursday instead of Friday, and Tisha b’Ov shall be on Friday at which time we can use microphones & subtitles. We may just need a short while to make Shabbos preparations & candle lighting before Tisha b’Ov celebrations are over.
