Hemera denotes a temporal day, whether a measured span, a recurring daily setting, or an identified occasion in Scripture.

The supplied verses most often use the term for measurable spans of time, including numbered, repeated, and limited periods. It also marks recurring daily activity, specified occasions such as the day of judgment or the Lord, broader eras described as “days,” and the contrast between daytime or light and night.

1. Measured spans and dates · dominant

   Plural forms mark durations and timeframes: in Acts 1:3 the APB renders an appearance “during forty days,” while Acts 16:12 and Acts 18:18 describe remaining “for some days” and “for many days.” Singular forms can identify a numbered point in time, as in 1 Corinthians 15:4, rendered “on the third day.”

2. Designated future or evaluative occasion · common

   The singular noun identifies an occasion characterized by what occurs there: in 1 Corinthians 3:13 the APB renders that the day will disclose each person's work and test it by fire. Other clauses name “the day of judgment,” “the day of the Lord,” or “the day of God,” connecting the term with judgment, salvation, coming, or glorification.

3. Recurring daily rhythm · occasional

   The term marks repeated activity across successive days. In 1 Thessalonians 2:9 the APB renders labor “night and day,” and in 2 Corinthians 4:16 it renders renewal “day by day”; 1 Corinthians 15:31 similarly places dying in an every-day pattern.

4. An era or period characterized as days · occasional

   Plural forms can locate events within a broader period rather than count individual units. In 1 Peter 3:20 the APB renders “the days of Noah,” while 2 Timothy 3:1 and 2 Peter 3:3 speak of “the last days”; Acts 11:27 uses “In those days” to set a narrative time.

   1 Peter 3:202 Timothy 3:12 Peter 3:3Acts 11:27Acts 15:7
5. Daytime or the sphere of light · rare

   In contrast with night and darkness, the noun marks daytime or an identified sphere of light. In 2 Peter 2:13 the APB renders reveling “in the daytime,” while 1 Thessalonians 5:5 and 1 Thessalonians 5:8 contrast belonging to the day with night or darkness.

   2 Peter 2:131 Thessalonians 5:51 Thessalonians 5:8

In the Anselm Project Bible: The APB commonly presents the term with “day” or “days,” including “on the third day,” “night and day,” and “the day of judgment.” Its wording only confirms the temporal setting of the clauses rather than fixing a separate English rendering in every instance.
