I think Shmuel would have specified that he was thinking about, say, the Hebrew lunisolar calendar.
For it in its traditional form there is a minor complication. Its day is divided into 24 hours like that of the Gregorian calendar; but there are neither minutes nor seconds. Instead each hour is divided into 1080 halaqim, one of which is 3.5 seconds in length. Apart from the use of this different unit, which poses no real difficulties, conversion from one calendar to another is not problematic. One converts an HCD into Gregorian days and then converts this GD value into a GCD and vice versa. (One could instead use Hebrew days, HDs, defined them as the number of elapsed days since the Hebrew-calendar epoch origin, the Gregorian date of which is -3730 September 7; but the results obtained would be the same. It all goes very nicely in fullword binary integer arithmetic.)
