From d4489f24a05911d1395e8473fe86c3442d9397ee Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 2 Feb 2026 12:22:03 +0000 Subject: fix(study): use date-based comparison with 3 AM boundary for due cards Instead of comparing due timestamps exactly (card.due <= now), compare against the next 3 AM boundary so all cards due within the current study day appear at once. This prevents new cards from trickling in throughout the day when FSRS fuzz spreads due times. https://claude.ai/code/session_01FeDztLcyGofd6nxh8ct7a3 --- src/client/pages/DeckDetailPage.tsx | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'src/client/pages') diff --git a/src/client/pages/DeckDetailPage.tsx b/src/client/pages/DeckDetailPage.tsx index be4dc90..97f8378 100644 --- a/src/client/pages/DeckDetailPage.tsx +++ b/src/client/pages/DeckDetailPage.tsx @@ -7,6 +7,7 @@ import { FontAwesomeIcon } from "@fortawesome/react-fontawesome"; import { useAtomValue } from "jotai"; import { Suspense } from "react"; import { Link, useParams } from "wouter"; +import { getEndOfStudyDayBoundary } from "../../shared/date"; import { cardsByDeckAtomFamily, deckByIdAtomFamily } from "../atoms"; import { ErrorBoundary } from "../components/ErrorBoundary"; import { LoadingSpinner } from "../components/LoadingSpinner"; @@ -27,9 +28,9 @@ function DeckHeader({ deckId }: { deckId: string }) { function DeckStats({ deckId }: { deckId: string }) { const { data: cards } = useAtomValue(cardsByDeckAtomFamily(deckId)); - // Count cards due today - const now = new Date(); - const dueCards = cards.filter((card) => new Date(card.due) <= now); + // Count cards due today (study day boundary is 3:00 AM) + const boundary = getEndOfStudyDayBoundary(); + const dueCards = cards.filter((card) => new Date(card.due) < boundary); return (
