Set Eggs Evening question

[CluckCluck2]

I set our eggs Oct 11 about 11 pm. We had a few issues with temps but candling showed several viable eggs. Since it was so late in the evening should lockdown be Friday the 28th at the same time?

I would just lock down in the next morning, thats what I did and they started hatching that evening after locking them down

No matter what time of day I set my eggs I go into lockdown on day 18 or 19. It doesn't affect my hatches any.
