In Cypher Sleuthing: Dealing with Dates, Part 4, we explore how to combine duration functions and components to translate durations across component categories. This allows for conversions among units within a group, such as days to weeks or months to years. The article also presents two challenges: one involving Postgres SQL ranges and the other visualizing progress through the year on a weekly basis using Cypher characters. Solutions are provided for both challenges, offering insights into efficient query writing and problem-solving with Cypher's temporal data capabilities.
