I created a new holiday calendar for the current year, and now holidays from prior years no longer display in People Schedule, why?

Question

I created a new holiday calendar for the current year, and holidays from prior years are no longer showing in People Schedule or impacting team member Availability in Utilization reporting. Why?

Answer

If a new calendar is created/used each year, and contains only that year's holidays, prior year/s holidays will no longer be visible in the heatmap, and subsequentially will no longer reduce team member availability or impact utilization.

To maintain accurate historical utilization reporting, we recommend creating a single calendar and maintaining it by updating/importing the public holidays each year.  Doing so will retain the holidays from past years while also adding the new, upcoming holidays for the current year.
