Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

NTP = Day 1 or Day after NTP as day 1, which more common?

If a contract states something like “Within 154 days after proceed date in LNTP” - in this case would use the day after NTP as Day 1.  How ofter do you count NTP as day 1 vs the day after.  I know using NTP as day is less hassle, if using the next day you actually need two milestones to get the roll-up count to work better, but still a hassle.  People think they are doing the contractor a favor by making the next day - day 1, but it is more of hassle on the schedule.

On the contract it clearly states where the NTP sits. Typical contracts states NTP + (no of days). The reason behind is NTP served at what time? For sure is not the first thing in the morning therefore it is common sense that it will be count day after the NTP is being serve.
