FAQ

Questions Cycle Day Resolver owners ask.

  • 01

    How does the cycle resolution logic work?

    The engine calculates the number of days elapsed between your anchor start date and the target date, then finds the remainder when divided by the total cycle length to identify the correct step.

  • 02

    Can I use this for skincare routines?

    Yes, you can provide a cycle array like ['Retinol', 'Exfoliant', 'Recovery'] and an anchor date to determine exactly which product to use on any future morning.

  • 03

    What happens if the target date is before the start date?

    The get_step_for_date capability will return an error stating that the target date must be equal to or later than the anchor date.
