⚡ Project Management Tool
Project End Date
Calculator
Instantly calculate your project's contractual completion date. Accounts for NTP-based scheduling logic used in real construction and infrastructure contracts.
One of the most common scheduling mistakes happens right at the beginning — incorrectly counting the first day of your project duration. Whether your contract counts the NTP date as Day 1, or the clock starts the following day, can shift your entire project end date by one full calendar day.
Use this tool to calculate your precise project end date based on your contract's NTP logic.

How does your contract count the project duration?
This determines whether the NTP issue date is Day 1 of the contract, or if the clock starts the following day.

Key Takeaways
- Always check your contract language. Terms like "within X days of NTP" or "commencing on the date of NTP" directly determine which rule applies.
- The NTP Day-1 rule is common in public sector contracts. Many government and infrastructure contracts treat the NTP issuance date as Day 1, effectively shortening your usable duration by one day.
- Contractual end date ≠ substantial completion date. Your baseline schedule should reflect the contractual end date, with float protecting against delays.
- Document your assumption. The NTP logic you apply should be documented in your Schedule Basis Memorandum and agreed with the client before baseline approval.
