Duration


Definition:

  • (n.) The state or quality of lasting; continuance in time; the portion of time during which anything exists.

Ephemeral


Definition:

  • (a.) Beginning and ending in a day; existing only, or no longer than, a day; diurnal; as, an ephemeral flower.
  • (a.) Short-lived; existing or continuing for a short time only.
