Titus Flavius Clemens (c.150 - 215) is also known as Clement of Alexandria...
...he made the following statement...

"THE MONTH AND THE MOON. AND IF THE MOON BE NOT VISIBLE, THEY DO NOT HOLD THE SABBATH, WHICH IS CALLED THE FIRST, NOR DO THEY HOLD THE NEW MOON, NOR THE FEAST OF UNLEAVENED BREAD, NOR THE FEAST NOR THE GREAT DAY."

Titus comments can best be understood with reference to a Lunar calendar.



THE SABBATH, WHICH IS CALLED THE FIRST...
...must be referring to the first weekly Sabbath of the month on day 8...
...which he mentions separately to the NEW MOON day which is day 1.

The NEW MOON day is the first day following the sighting of the New Moon...
...notice on the calendar day 'one' is in the Sabbath column...
...and is always a day of rest, although not called a Sabbath.

The NEW MOON day is not technically a Sabbath because it does not follow six days of work...
...you can see this on the second month Lyar, it has 30 days...
...there has been a weekly Sabbath on the 29th day, so there is only one work day before the New Moon day...
...in 29 day months the fourth Sabbath of the month is followed by New Moon day, both rest days...
...that begins again the succession of 'weekly' Sabbaths etc.

The point is that Titus is making reference to the NEW MOON day of the Lunar calendar...
...which is then followed by six work days and the first 'weekly' SABBATH, WHICH IS CALLED THE FIRST.

This then sets the timing of THE FEAST OF UNLEAVENED BREAD determined by the NEW MOON.

Then Titus says, NOR THE FEAST NOR THE GREAT DAY which is Passover and the feast of Passover...
...Passover is both an event and a feast timed from the first New Moon of the year.

Titus is then saying that IF THE MOON BE NOT VISIBLE, THEY DO NOT HOLD THE SABBATH...
...they therefore wait until a visible New Moon to begins Israel's year and succession of weekly Sabbaths.
