The Date-ing Game
summary
Explains concrete pitfalls and fixes when apps handle time: how Date vs DateComponents and Calendar-aware formatting map differently to user intent, when to treat an event as an absolute instant versus a local calendar day, and why leap years, leap seconds, Arizona no-DST and staggered daylight‑savings dates break naive code. Draws on real bugs from a parking app and a journaling app, shows using Date, Calendar, Formatter, TimeZone and test borders and daylight rules to make things reliable.
