Rhaenyra searched for Luke for about a few days to a week , based on fan discussion and recap-style commentary rather than an exact on-screen timeline. The show does not give a precise count, so the safest read is that her search was brief but intense, and her absence was noticeable.

What the timeline suggests

  • Luke dies at the end of season 1, and Rhaenyra’s immediate reaction follows right after that event.
  • A later discussion of the scene describes her absence as “days or a week,” not a long stretch.
  • There is no official exact number stated in the sources I found, so any tighter estimate would be speculation.

In context

The emotional point of the scene is that Rhaenyra doesn’t spend a huge amount of time searching before the story pivots into grief and war. That short window makes the loss feel sudden and destabilizing rather than like an extended rescue mission.
