Configuring Custom Dates in Foundation Hub

All units in Study Design and Tracking, and their conversions, are defined in Foundation Hub. You can configure Foundation Hub to employ a custom calculation of dates for studies using month intervals for time points. By default, the month time unit in Foundation Hub is based on a 365-day year. If you want to use a year length averaged to account for leap years, with 365.25 days, you can add a custom time unit for months.

Context: The calculation for the default conversion factor between months and seconds (the base unit in Study Design and Tracking) is:

Conversion Factor = (days in a year/months in a year) x (seconds in a day) = (365/12) x 86400 = 2628000

To use 365.25 days in a year the calculation is:

Conversion Factor = (365.25/12) x 86400 = 2629800
