Here is the schedule taken from a Dhamma book in Thai language of an abbot of a temple:
2- 4am : Wake up and prepare for pindapat (alms round)
4-5am : Assemble the monks. Some monks have to walk a distance from their dwelling place to the sala to prepare
6am : Go for pindapat (alms round)
7.30am : Partake in the daily meal (only one solid meal a day)
11am : Self practice doing walking and/or sitting meditation
3pm : Sweep the monastery area
4 - 5pm : Take a bath and freshen up
6pm : Chanting and teaching Dhamma to the laypeople
10.30pm: Short sitting or walking meditation
My apologies, I do not know the name of the abbot. The information above was translated to me by a Thai Buddhist friend.
However, most abbots in forest monasteries spent very little time on sleep- on average it is between 2 to 4 hours.
