Watchman Nee (in a book I'm reading) sounds like he said Jesus was on the cross for 6 hours.
"So far as the experience of co-death in the Christian life is concerned, it is mainly included in this representative period six hours."
I checked the account of the Passover on this matter, in Numbers 9.
Num 9:3
3 In the fourteenth day of this month, at even, ye shall keep it in his appointed season: according to all the rites of it, and according to all the ceremonies thereof, shall ye keep it.
KJV
Num 9:12
12 They shall leave none of it unto the morning, nor break any bone of it: according to all the ordinances of the passover they shall keep it.
KJV
But according to this chart I found online, it sounds like He was dead on the cross for 3 hours, judging by the details of the Passover, as to having started in the evening, and that eating of it was to finish before morning. So maybe he guessed a bit incorrectly, as to how long Jesus was dead on the cross.
