## Overview

The Date Range Validator is a precise utility designed to verify whether a list of dates falls within a specific start and end date boundary. It simplifies data auditing by instantly flagging which entries are compliant and which fall outside your defined timeframe.

## Inputs

- **Start Date** (text): Enter start date (e.g., 2024-01-01)
- **End Date** (text): Enter end date (e.g., 2024-12-31)
- **Test Dates** (textarea): Enter dates to validate (one per line)

## When to use

- Verifying if project milestones or task deadlines fall within a fiscal quarter.
- Filtering user-submitted birth dates or event logs against a required eligibility window.
- Cleaning datasets by identifying and removing entries that exist outside a specific operational period.

## How it works

- Enter your target start and end dates to define the valid timeframe.
- Paste the list of dates you wish to check into the test field, placing each date on a new line.
- Submit the form to receive a validation report confirming which dates are within range and which are outside.

## Use cases

- Auditing employee attendance logs against a specific pay period.
- Validating subscription expiry dates against a current marketing campaign window.
- Ensuring historical transaction records fall within a specific tax year.

## Frequently asked questions

### What date format does the tool support?

The tool supports standard YYYY-MM-DD date formats for consistent validation.

### Can I check dates that are exactly on the start or end date?

Yes, the validator includes the start and end dates as part of the valid range.

### Is there a limit to how many dates I can validate at once?

You can paste as many dates as you need, provided they are separated by new lines.

### Does this tool modify my original data?

No, the tool only performs a validation check and does not alter your input data.

### Is the validation case-sensitive?

Date validation is numeric and format-based, so case sensitivity does not apply.
