In `@js/app.js`:
- Around line 398-399: The export logic uses currentView.length to decide
between currentView and checks, causing exports to revert to all checks when
filters return zero results; change the condition to detect whether filters are
active instead of whether currentView has items—e.g., replace the ternary for
dataToExport so it chooses currentView whenever an active filter flag or the
filters collection (e.g., activeFilters, filters, hasActiveFilters) indicates
filters are applied, otherwise use checks; update the assignment that defines
dataToExport and ensure it references the existing filter-state variable rather
than currentView.length.
- Line 228: The dueDate string (YYYY-MM-DD) is being passed directly to Date
which parses as UTC; instead parse it as a local date by splitting the string
and constructing with new Date(year, monthIndex, day) before using it in
formatDate and daysUntil. Update all usages where check.dueDate is passed (e.g.,
the template expression that calls formatDate(check.dueDate) and any calls to
daysUntil(check.dueDate)) to first convert check.dueDate into a local Date
object (parse year, month, day and call new Date(year, month-1, day)) and then
pass that Date to formatDate/daysUntil so rendered dates and calculations are
correct in local time zones.

🧩 Analysis chain
🌐 Web query:
In JavaScript, does new Date("2026-05-04")parse as UTC or local time, and what are the timezone implications for values?
💡 Result:
new Date("2026-05-04") parses the date-only string as a UTC date (midnight UTC), not as local time. JavaScript’s Date parsing treats “date-only” ISO 8601 forms (YYYY-MM-DD) as UTC; in contrast, date-time forms without an explicit timezone are interpreted as local time.[1] Timezone implications for : 1) The value string (the.value / submitted value) is always the calendar date in yyyy-mm-dd, with no timezone information.[2] 2) If you use the DOM convenience APIs to convert the value to a Date (HTMLInputElement.valueAsDate), the returned Date object “should always be interpreted as a UTC time” (midnight UTC). MDN warns that if you instead interpret it as local, you can be off by 1 day (e.g., for negative UTC offsets, “local” interpretation can shift to the previous day).[3] Practical takeaway: - If your goal is to treat dates as calendar days (not instants in time), keep them as yyyy-mm-dd strings from the input, or when converting to/from Date objects, use UTC getters/setters (getUTCDate, setUTCDate, etc.) for the “day” part to avoid off-by-one errors.[3] Example pattern (UTC-safe for day-only): - Read: const s = input.value; // "2026-05-04" - Convert to Date instant at midnight UTC: const d = new Date(s + "T00:00:00Z"); (this makes the UTC intent explicit, avoiding the historical date-only parsing quirks).

Parse date-only values as local dates before using them here.
dueDate is a YYYY-MM-DD string, and new Date("2026-05-04") is parsed as midnight UTC in browsers. In US time zones, this shifts both the rendered date and the daysUntil() result by a day, so "Due this week" can be wrong even when the stored date is correct.
Suggested fix
+function parseLocalDate(dateValue) {
+ const [year, month, day] = dateValue.split("-").map(Number);
+ return new Date(year, month - 1, day);
+}
+
function daysUntil(dateValue) {
const today = new Date();
- const target = new Date(dateValue);
+ const target = parseLocalDate(dateValue);
const difference = target.getTime() - today.getTime();
return Math.ceil(difference / 86400000);
}
function formatDate(dateValue) {
if (!dateValue) {
return "No date";
}
return new Intl.DateTimeFormat("en", {
month: "short",
day: "numeric",
year: "numeric",
- }).format(new Date(dateValue));
+ }).format(parseLocalDate(dateValue));

Don't fall back to all checks when a filtered view is empty.
If filters are active and produce zero matches, currentView.length is 0, so this exports checks instead of the empty filtered result the UI is showing. Base the choice on whether any filters are active, not on whether the filtered list is non-empty.
Suggested fix
