Example use cases
Quarterly revenue report bucketing
“I'm building a revenue report and need to know which calendar quarter each sale date falls in — can you tell me what quarter 2025-11-22 is in?”
Goal tracking period assignment
“We track OKRs by quarter. What quarter of the year is 2026-02-10 in so I can file it under the right goal cycle?”
Finance dashboard date classification
“My finance dashboard needs to bucket transactions by Q1–Q4. What quarter does the date 2024-07-04 belong to?”
