+- `getTodayISO()` → Returns today's date in `YYYY-MM-DD`
+- `getTodayReadable()` → Returns today's date in human-readable string (`Sat Oct 04 2025`)
+- `getCurrentYear()` → Returns current year as a number
+- `formatUnixTimestamp(unixSeconds)` → Converts UNIX timestamp into `{ fullDateTime, date, time }`
+- `formatDateTime(jsDate)` → Converts JS Date/string into `"YYYY-MM-DD HH:mm:ss"`
