CALCULATORS
1. Actual Age Calculator - Update - the excel calculator was updated to reflect the actual age plotting of the growth chart - June 16, 2013. To download the excel calculator that will allow you to calculate exact percentiles and z-scores for infants, click here (bug fixed Sept 28): 
2013 Actual age Percentile and z-score Calculator 

2. Research Bulk Calculator - for weight, Head circumference, and Length - can calculate up to 500 babies' completed weeks z-scores and exact percentiles at one time (January 2014). Many thanks to Dr. Tim Stevens for his assistance in preparation of this spreadsheet. 
These results differ from the Actual Age Calculator since they are based on Completed weeks (24 weeks and 0 to 6 days are categorized as 24 weeks), which is usually of utility for research purposes:
