Rules for writing correct date code in this project. The server stores all data in UTC — all date arithmetic, comparisons, and state must use UTC methods, never local time methods.

Wire a frontend page in the Authgear Site Admin Portal to the real Site Admin API, replacing mock data from src/data/. Use this skill when asked to connect a page to the API, replace dummy/mock data with live data, implement an API call on a screen, or fetch real data for any page in this project.
Update vulnerable npm dependencies safely. Only applies non-breaking changes. Prefers lock-file-only fixes via `npm audit fix`. Generates a summary of what was updated, what was skipped, and why. Use when asked to fix security vulnerabilities, run dependabot-style updates, or update vulnerable packages.
Write unit tests for API integration code. Required for all changes to src/api/

The server stores all data in UTC. Always use UTC methods. Never use local date methods.
| Use | Avoid |
|---|---|
getUTCFullYear() | getFullYear() |
getUTCMonth() | getMonth() |
getUTCDate() | getDate() |
setUTCDate() | setDate() |
setUTCFullYear() | setFullYear() |
Date.UTC(y, m, d) | new Date(y, m, d) |
toISOString().slice(0, 10) is correct only when d is already a UTC midnight date:
const toDateStr = (d: Date) => d.toISOString().slice(0, 10);
const now = new Date(); // current moment — UTC methods give the correct UTC date
When building a range that needs UTC midnight explicitly:
new Date(Date.UTC(now.getUTCFullYear(), now.getUTCMonth(), now.getUTCDate()))
toLocaleDateString)Always pass timeZone: "UTC" so the displayed date matches the stored UTC date:
d.toLocaleDateString("en-US", {
month: "short",
day: "numeric",
year: "numeric",
timeZone: "UTC",
});
Calendar interprets its value prop as local time. This is the only place local date methods are allowed.
Reading from Calendar (onSelectDate) — normalize to UTC midnight immediately:
onSelectDate={(date) => {
setDate(
new Date(Date.UTC(date.getFullYear(), date.getMonth(), date.getDate()))
);
}}
Writing to Calendar (value) — convert UTC midnight back to local midnight so the widget highlights the correct day:
value={
utcDate
? new Date(utcDate.getUTCFullYear(), utcDate.getUTCMonth(), utcDate.getUTCDate())
: undefined
}
