Quick Calendar

Use to display an interactive calendar widget when the user needs visual date navigation. Call this tool for requests to open a calendar, browse years/months/days, jump to specific dates, or inspect temporal context in a structured layout. The optional initialPeriod input sets where the widget opens and must be formatted as YYYY, YYYY/M, or YYYY/M/D. If the user gives only a year, open the year view context for that year. If the user gives year and month, open month context for that month. If the user gives a full date, open day context for that date. If no period is provided, default to the current year/month based on the user's timezone when available, or UTC otherwise. Prefer this tool when a visual calendar is more useful than plain text and avoid it for unrelated requests that do not involve dates or scheduling context.
