If you want 0 as the day argument, you tell Excel that you the day prior to the first day of the month. To convert if you want it to current UTC time, you need to compensate for the UTC leap seconds, by J prior to the restart of the calculation (however, this adjustment does not require a lookup table, since the switching by the second predictable with a simple formula); you'll also need to eventually determine which of the two possible UTC date and time is used in times where leap seconds are added (no final compensation is needed, if there are negative leap seconds occur the could be on the rare days that is shorter than 24 hours). Nevertheless, he dated twice, most of the nightly observations with the two Egyptian days, starting at sunrise and Babylonian days beginning at sunset. The meridian of Alexandria is chosen, that is related of Ptolemy to the beginning of the era of Nabonassar, the basis of all his calculations. Now, at 11:00, and Sunday 22.
