καιρός

G2540 names a time, season, appointed occasion, or fitting opportunity. Eighty-five primary forms occur in eighty verses across nineteen books. The word can refer to ordinary seasons, harvest time, a convenient opportunity, a temporary period, the right time for action, a divinely fixed time, the present age, or an eschatological moment. Mark 1:15 announces that the time is fulfilled and God's kingdom is near. Acts 1:7 says that times and seasons are fixed by the Father's authority and are not given to the disciples to know. Other passages speak of Christ dying at the right time, a time of favor, due time for harvest, a moment for faithful conduct, and the time of judgment.

G2540 is often contrasted with G5550 as meaningful or opportune time versus measured duration. That contrast may help in some passages, but the words overlap and do not establish two absolute kinds of time. Nor does every G2540 occurrence carry equal eschatological weight. Context distinguishes fig season, harvest, personal opportunity, historical period, and God's saving appointment. The word calls for discernment and trust, not speculative date-setting or productivity pressure. A traditional-only row at John 5:4 remains outside the primary count.

G2540 ranges across seasons, opportunities, fixed periods, saving moments, present responsibility, and final expectation. God determines many of these times, while people are repeatedly called to recognize and answer the moment faithfully.
