'Third' in the Bible

These people are not drunk, as you assume, since it is [only] the third hour of the day (9:00 a.m.);

God raised Him [to life] on the third day and caused Him to be plainly seen,

and there was a young man named Eutychus (“Lucky”) sitting on the window sill. He was sinking into a deep sleep, and as Paul kept on talking longer and longer, he was completely overcome by sleep and fell down from the third story; and he was picked up dead.

Then summoning two of the centurions, he said, “Have two hundred soldiers ready by the third hour of the night (9:00 p.m.) to go as far as Caesarea, with seventy horsemen and two hundred spearmen;

and on the third day they threw the ship’s tackle (spare lines, blocks, miscellaneous equipment) overboard with their own hands [to further reduce the weight].
