You do the math.
Passover dates 26-34 A.D.
The following astronomical data in the first three columns below was obtained from the U.S. Naval Observatory Astronomical Applications Department. The pertinent file may be accessed on the Internet at http://www.usno.navy.mil/USNO/astronomical-applications/data-servic... .
Note. The times of day given in the second and third columns have been adjusted +2 hours from U.S. Naval Observatory figures to account for the difference between Jerusalem Israel and Greenwich England (universal) time.
It should also be noted that the first evening of a visible crescent moon (column 4) always occurs only minutes after sundown, which is at the very beginning of a new day on the Hebrew calendar. This Hebrew day correlates to the following day on our Gregorian calendar as noted in the chart below (column 5). Column 6 is Passover dates for the given years.

To understand the timing of the annual feast days, one must first understand the principles used in the Hebrew calendar for the purpose of determining the day of the creation week on which these various annual festivals would actually occur.
These principles apply to both the original Hillel I calendar used from the time of Moses through the time of Christ until the middle of the fourth century, and also the Hillel II calendar used from the fourth century until today, and onward into the distant future.
One of these important principles is in reference to the beginning point of the year. The ancient calendar began the year on the first new moon of spring, or after the spring equinox, while the more recent calendar begins the year at the new moon nearest the spring equinox, which in some years would actually fall before the spring equinox. Therefore, in some years both calendars begin the new year on the same new moon after the spring equinox, while in other years the beginning points of the year would be on different new moons, one month apart.
In the year 31 C.E., which year was in the middle of the typical “week of years, the Passover occurred on a Friday, the first day of the Feast of Unleavened Bread occurred on a Saturday, a 7th-day Sabbath, and the Wave Sheaf offering occurred on the 16th day of the Hebrew month, which is always the second day of the Feast of Unleavened Bread, a Sunday, or first day of the creation week in that particular year.
Each of the types occurred on the actual anti-type. The “shadow” Sabbaths within the old sanctuary system occurred on 7th day Sabbaths that particular year.
Both the Hillel I and Hillel II Hebrew calendars sometimes determine the new moon by the night of the conjunction or sometimes by the first sighting, that would rule the night, depending, of course, on the location of the seventh day Sabbath of the creation week in relation to that new moon, and or in relation to the Day of Atonement.
For example see the dates for the Day of Atonement in the year 1987, then look at 2028, both occur on the Holy seventh-day Sabbath, the new moon for the seventh month in 1987 was determined basically by the conjunction of the new moon, ware as in 2028 the new moon of the seventh month occurs when a very large sliver is disable, so that the Day of Atonement could fall on the Holy seventh-day Sabbath.
So we can see the new moon for the first month in the year 31 C.E. when type met anti-type was the same large sliver as the new moon of the seventh month will be in the year 2028.
Unless we understand these principles, we could end up being confused, and end up with the wrong conclusions, such as we see all around us.
In the year 27 C.E. the conjunction of the new moon of the seventh month was used, and the day of Atonement occurred on a seventh-day Sabbath that year, when type met anti-type (the shadow Sabbath fell on a seventh-day Sabbath that particular year)
