Let me Count the Days

The following websites provide good resources for calculating days and dates on public works construction projects.

Calculating number of days between two dates: If you want to calculate the number of days from the Notice to Proceed to the completion date, go to the following website address: http://www.timeanddate.com/date/duration.html. If the “from” date is the Notice to Proceed date and to “to” date is the completion date, remember that you will need to add one day to the result in order to account for the actual day of the Notice to Proceed.

Calculating a date based on number of days: If you want to calculate the completion date from the Notice to Proceed date based on the number of days allowed, go to the following website address: http://www.timeanddate.com/date/dateadd.html. You will need to subtract one day from the result, again in order to account for the actual day of the Notice to Proceed.
