"The Hebrew Calender" searched in The Tanakh @ 86423 skip
This is the only time "The Hebrew Calender" shows using 'The Keys to the Bible'.

No big odds on the main term, 1 in 10, but it almost intersects the expression "
the measure of my days", which
intersects with the Biblical name "
Ibneiah" which means "YHVH builds".

And has the word translated "
New Moon" twice.

The main term goes through Numbers 1.1, which mentions a date:

And the Lord spake unto Moses in the wilderness of Sinai, in the tabernacle of the congregation, on the first day of the
month, in the second year after they were come out of the land of Egypt, saying,    Numbers 1.1

And Ezekiel 42.20 which has the expression "
he measured":

He measured it by the four sides: it had a wall round about, five hundred reeds long, and five hundred broad, to make
a separation between the sanctuary and the profane place.
      Ezekiel 42.20

And Psalms 39.5 (which is 39.4 in The Tanakh) which has the expression "
the measure of my days", a perfect
description of the Calender:

Lord, make me to know mine end, and the measure of my days, what it is: that I may know how frail I am.    Psalms
