 ## Critical: Date/Time Handling
 
+**Bibdle is played by users across many timezones worldwide. The verse shown to a player must always be the verse for the calendar date at *their* location — not the server's timezone, not UTC. A user in Tokyo on Wednesday must see Wednesday's verse, even if the server (or a user in New York) is still on Tuesday.**
+
 **NEVER use server time or UTC time for user-facing date calculations.**
 
 - Get today's date client-side: `new Date().toLocaleDateString("en-CA")` → `YYYY-MM-DD`
 - Pass the date to the server as a query param or POST body (`localDate`)
 - Server-side date arithmetic must use UTC methods on the client-provided date string: `new Date(dateStr + 'T00:00:00Z')` + `setUTCDate`/`getUTCDate`
 - `src/routes/+page.ts` has `ssr = false` so the load runs client-side with the true local date
+- Never set the user-facing URL to include their date as a parameter. It should always be passed to an API route behind the scenes if needed.
+
+### Streak Calculation
+
+A streak counts consecutive calendar days (in the user's local timezone) on which the user completed the puzzle. The rules:
+
+- The client passes its local date (`localDate`) to the streak API. The server never uses its own clock.
+- A streak is **active** if the user has completed today's puzzle *or* yesterday's puzzle (they still have time to play today).
+- Walk backwards from `localDate` through the `dailyCompletions` records, counting each day that has a completion. Stop as soon as a day is missing.
+- A streak of 1 (completed only today or only yesterday, with no prior consecutive days) is **not displayed** — the minimum shown streak is 2.
+- "Yesterday" and all date arithmetic on the server must use UTC methods on the client-provided date string to avoid timezone drift: `new Date(localDate + 'T00:00:00Z')`, then `setUTCDate`/`getUTCDate`.
