Important Dates in the Lives of Jesus and Mary 

referring to the conception of John is the 24th verse (Luke 1:24). However, the arguments below take into 

account the possibility that John was conceived later than Tishri 24. 

The Incarnation of Jesus Christ 

    The sixth month of the Jewish civil calendar (AdarI) and Elizabeth's sixth month both contained the day of 

the Incarnation of Christ (Lk 1:26, 36). But the conception of John the Baptist by Zechariah and Elizabeth 

could have occurred no earlier than Tishri 24 and no later than the end of Tishri. So Elizabeth's first month 

began near the end of Tishri, the first month of the Jewish civil calendar. Her second month began near the 

end of the second month of the calendar, and so on. Elizabeth's sixth month began near the end of the sixth 

month of the Jewish civil calendar, AdarI. Since the Incarnation occurred during both Elizabeth's sixth month 

and the sixth month of the calendar (AdarI), the Incarnation must have occurred during the last few days of 

AdarI, on or after the 24th of the month. 

    The Incarnation of Jesus Christ also occurred in that same Sabbatical year (16/15 

B.C.

), a year of special 

blessings from God. The Jewish faith was designed to prepare for the coming of the Messiah, and the 

Sabbatical years and Jubilee years were a foreshadowing of the Blessing from God, Jesus Christ. How fitting 

then that the Messiah should begin His human life during a Sabbatical year. The year following that Sabbatical 

year was a Jubilee year (see chapter 16; see also Appendix I, Chart 7). The Jubilee year begins in the autumn 

in the month of Tishri. The Sabbatical year of 16/15 

B.C.

 was followed by the Jubilee year of 15/14 

B.C.

(Tishri of 15 

B.C.

 to Tishri of 14 

B.C.

). The Incarnation of Christ occurred during a  Sabbatical year and the 

Birth of Christ occurred during a Jubilee year. The Jubilee year was associated in ancient Jewish thought with 

the coming of the Messiah.

From the Incarnation to the Birth of Christ 

    The above time frame for the Incarnation (between AdarI 24 and AdarI 30) is based on my interpretation of 

the Gospel of Luke.

266

 Now, without using the information given to us by Blessed Anne Catherine, we can 

determine the approx. date of the Birth of Christ. The normal length of time from conception to birth is 266 

days, plus or minus 2 weeks; 90% of all children today are born within that time frame.

267

 Nine lunar months 

is 266 days, so that the ninth lunar month from the time frame of AdarI 24 30 is Heshvan 24 30. Adding and 

subtracting two weeks to this time frame gives us Heshvan 10 to Kislev 14 as the most probable time frame for 

the Birth of Christ. In 15 

B.C.

, Heshvan 10 coincided with Oct. 31 and Kislev 14 coincided with Dec. 4.

268

Using this determination, Christ was born sometime between Oct. 31 and Dec. 4, inclusive, in 15 

B.C.

 The 

date of Dec. 25 is three weeks beyond the usual time frame for birth and six weeks past the usual calculation 

for the due date of birth. The date of Dec. 25 is too late in the calendar year to fit the above date for  the 

Incarnation. Christ was not born on December 25. 

The Day and Month of the Incarnation 

     Last night I saw the Annunciation as a Feast of the Church, and was once more definitely informed that at 

this moment the Blessed Virgin had already been with  child for four weeks. This was expressly told me 

because I had already seen the Annunciation on the 25th of February, but had rejected the vision and had not 

related it. 

269

    Blessed Anne Catherine Emmerich received visions from God about the Annunciation, both on the actual 

day of the Annunciation, February 25, and on the day in the liturgical calendar when the Church celebrates 

the Annunciation, March 25. She at first rejected the vision given to her on February 25, because she had 

assumed that the Annunciation and Incarnation occurred on the same day as it is celebrated by the Church, 

March 25. But God informed her that the actual day of the Incarnation was four weeks earlier, on February 

25. 

    The Incarnation occurred sometime during the last few days of the month of AdarI. And Blessed Anne 

Catherine places the Incarnation on February 25. In the year 15 

B.C.

, February 25 fell during the last few days 

of the Jewish month of AdarI, on AdarI 28.
