Back in 2012 or 2013.... when i did my climb. Below is the ideal schedule i think.
Day 1: take flight in
take arranged transport(1-2hrs to reach) to hostel at the foot of K, buy what you need
while you are in the town area.
check in hostel, i remember by the time we reach it should be late afternoon.
just nice to eat late lunch i think. but
cos nightfall came pretty quickly.
Day 2: check out of hostel early early , take their short distance van or something i can't rem. I think there is breakfast provided. after that, You need to rush to booking office to book your guide/s and porters (if u need ) and weigh your baggage (if you need them to carry it).
Setoff early, you should reach the night resting dorm around 1-5pm, depending on your speed of ascent
Check-in @dorm , eat dinner and sleep by 9-10pm .
Day 3: wake at 12MD or 1am, eat breakfast in 30 mins. and leave by 1.30am with your lightly packed backpack.
reach last checkpoint prior to 5am, else they won't let you up.
reach the top and leave by 7am.
depart and reach dorm around 10am-12noon , check out, eat lunch and depart by 1pm latest
Reach the foot by 5pm -7pm.
Arrange transport (1-2hrs) ride back to town. Stay over 1 nite at the hotel in town.
Day 4 : Eat breakfast and leave to catch your morning flight to SG.
Sorry to be longwinded, recalling it from memory...my KK trip was a horror story and we trek down K in pitch darkness.
