Critical hours Mention in the Besorat Tova (Gospels) Map out in modern day clock

The concept of dividing the daylight and night periods into 12 numbered hours each did not exist in ancient Israel during the Tenakh period. It was a later Greek and Roman development that the Jewish people adopted during the Second Temple period (which is why you see numbered hours frequently mentioned in the New Testament and the Talmud). 

The critical hours mentioned in the Besorat Tova (Gospels) map out precisely to our modern day clock:

• The First Hour: 6:00 AM – 7:00 AM (The dawn of the working day).
• The "Second hour" refers to approximately 8:00 AM. Not mention in the Bible. Because the daylight period was divided into 12 equal hours starting at sunrise (roughly 6:00 AM), the calculation is simple: 6:00 AM + 2 hours = 8:00 AM.
• The Third Hour: 9:00 AM (The time of the morning Shacharit sacrifice in the Temple; also the hour the Ruach HaKodesh was poured out at Shavuot/Pentecost).
• the "Fourth hour" corresponds to approximately 10:00 AM.This is calculated by starting at sunrise (roughly 6:00 AM) and counting forward four hours (6:00 AM + 4 hours = 10:00 AM). explicitly mentioned in ancient Jewish texts outside scripture, such as the Mishnah and Talmud, because it marked a major daily legal deadline:
• the "fifth hour" (sha'ah chamishit) corresponds to approximately 11:00 AM. This is calculated by starting at sunrise (roughly 6:00 AM) and counting forward five hours (6:00 AM + 5 hours = 11:00 AM). It represents the late morning hour just right before the sun reaches its highest point at noon (the sixth hour).The fifth hour is specifically designated as the time when Jews must stop eating it, finish burning or destroying it, and declare it nullified.
• The Sixth Hour: 12:00 PM (Noon) (The zenith of the sun). This is exactly when Yeshua, exhausted from the journey, sat down at Ya‘akov’s Well in Sychar (Yochanan 4:6). In Judean culture, women typically drew water at the first or eleventh hour to avoid the heat; drawing at the sixth hour highlights the Samaritan woman’s deep social isolation.
• The Seventh hour" (sha'ah shevi'it) corresponds to approximately 1:00 PM (specifically 12:30 PM and onward) Healing of the Royal Official's Son exact time is found in John 4:46-54 "Yesterday at the seventh hour the fever left him.
• the "Eighth hour" (sha'ah sheminit) corresponds to approximately 2:00 PM This is calculated by starting at sunrise (roughly 6:00 AM) and counting forward eight hours (6:00 AM + 8 hours = 2:00 PM). It represents the mid-afternoon, a time deeply tied to the daily operational rituals of the Jerusalem Temple and Rabbinic tradition.
• The Ninth Hour: 3:00 PM (The time of the afternoon Minchah sacrifice; the traditional hour of prayer, and the exact moment Yeshua cried out and gave up His spirit on the execution stake).

• "the tenth hour" refers to approximately 4:00 PM under the traditional Jewish method of timekeeping, which divided the daylight period into 12 equal hours starting at sunrise (around 6:00 AM). 
• The Eleventh Hour: 5:00 PM (The final hour of the agricultural workday before twilight).

1. General Descriptions of the Day

The ancient Israelites tracked time using natural markers, daily milestones, or Temple rituals: 

• "The morning" (Boker)
• "The heat of the day" (Chom hayom) — roughly midday
• "Noon" (Tzohorayim)
• "The evening" (Erev)
• "Between the evenings" (Bein haarbayim) — twilight/dusk 

2. The Three Night Watches

While the day was not broken into hours, the night was divided into three military "watches" (Ashmoret), which are mentioned in the Tanakh: 

• The First / Beginning Watch (Rosh ashmoret): Mentioned in Lamentations 2:19.
• The Middle Watch (Ha'ashmoret hatichonah): Mentioned in Judges 7:19.
• The Morning Watch (Ashmoret haboker): Mentioned in Exodus 14:24 and 1 Samuel 11:11.

The Only Exception: The Aramaic of Daniel

The closest the Tanakh ever gets to the word "hour" is the Aramaic word Sha'ah (שָׁעָה) in the Book of Daniel (e.g., Daniel 3:6, 4:16). However, linguists note that in the Tanakh, sha'ah does not mean a 60-minute or technical hour; it simply translates idioms meaning "instantly," "immediately," or "a brief moment."

Midrashic Tradition: The Creation Timeline of Adam

The eighth hour carries an interesting chronological placeholder in Jewish Rabbinic literature regarding the day Adam was created. In the Babylonian Talmud (Sanhedrin 38b), Rabbi Yochanan bar Chanina maps out the first 12 hours of the life of Adam on the sixth day of creation: 

• First Hour: His dust was gathered.
• Fifth Hour: He stood on his feet.
• Seventh Hour: Eve was paired with him.
• The Eighth Hour: "They entered the bed as two and descended as four"—marking the physical union of Adam and Eve and the immediate birth of their first children, Cain and Abel, before the subsequent fall in the tenth hour.
