What Is Date Range Generator?
The Date Range Generator produces a list of all dates falling within a specified range, with configurable step size, step unit, output format, and weekend exclusion. Enter a start and end date, choose whether to step by days, weeks, or months, set the step interval (e.g., every 2 days), and select your preferred output format (ISO, US, European, long, or short). Optionally exclude weekends for business-day-only lists. The generated list can be copied to the clipboard with one click for use in spreadsheets, scripts, reports, or data entry. A safety limit of 1,000 dates prevents excessive generation for very large ranges.

Technical Guide
The generator initializes with the start date and iterates forward, adding the step amount in the specified unit on each iteration, until exceeding the end date or reaching 1,000 dates. For day steps, it uses setDate(getDate() + step). For week steps, setDate(getDate() + step * 7). For month steps, setMonth(getMonth() + step). The weekend exclusion filter checks getDay() !== 0 && getDay() !== 6 after each date is computed but before adding it to the results. The format function constructs the output string using getFullYear(), getMonth()+1, and getDate() with appropriate separators and zero-padding. The clipboard copy joins all formatted dates with newlines.
