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.

Why Use Date Range Generator?

  • Configurable step size: every N days, weeks, or months
  • 5 output format options (ISO, US, EU, long, short)
  • Weekend exclusion for business-day lists
  • One-click copy of all dates
  • Handles up to 1,000 dates per generation
  • Perfect for spreadsheet data preparation

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.

Tips & Best Practices

  • 1
    Use ISO format (YYYY-MM-DD) for database-compatible date lists
  • 2
    Set step to 7 days for weekly date sequences
  • 3
    Enable weekend exclusion for business-day planning
  • 4
    The month step handles varying month lengths correctly
  • 5
    Copy the entire list and paste directly into spreadsheet cells

Frequently Asked Questions

Q Is there a limit to how many dates can be generated?
Yes, a safety limit of 1,000 dates prevents excessive generation. For most practical uses, this is more than sufficient.
Q Does the month step handle end-of-month correctly?
JavaScript's setMonth handles the overflow — stepping monthly from January 31 will skip to the last valid day of each subsequent month.
Q Can I generate bi-weekly dates?
Yes, set the unit to "weeks" and the step to 2 for bi-weekly (every other week) date generation.
Q What format works best for Excel?
ISO format (YYYY-MM-DD) or US format (MM/DD/YYYY) are both well-recognized by Excel. ISO format is recommended for unambiguous interpretation.
Q Can I exclude specific dates (like holidays)?
Currently the tool supports weekend exclusion only. For holiday exclusion, generate the list and manually remove holiday dates.
