Similarly, an HR manager might use conditional Formatting to track employee anniversaries or contract end dates, ensuring no key dates are missed.

Here's an in-depth look at how you can use conditional Formatting with date ranges in Excel:

1. Setting Up Basic Date Conditions:

- To highlight cells that contain today's date, you can use the formula `=TODAY()` in the conditional Formatting rules.

- For past dates, a formula like `=A1

- Future dates can be highlighted using `=A1>TODAY()`.

2. Working with Date Intervals:

- To format a range of dates within the next week, you could use `=AND(A1>TODAY(), A1<=TODAY()+7)`.

- For last week, the formula would be `=AND(A1=TODAY()-7)`.

3. Highlighting Specific Days:

- Weekends can be highlighted by using the `WEEKDAY` function: `=OR(WEEKDAY(A1)=1, WEEKDAY(A1)=7)`.

4. Using Conditional Formatting to Track Milestones:

- If you have a project deadline on June 30, 2024, you can highlight it with `=A1="2024-06-30"`.

5. Formatting Based on Other Cells:

- You can format a cell based on another cell's date. For example, if B1 is the deadline and A1 is the start date, use `=A1>B1` to highlight overdue tasks.

Example:

Imagine you're organizing a conference. You have a list of tasks with start dates and deadlines. By applying Conditional formatting, you can set up the sheet so that tasks due within the next 7 days are highlighted in yellow, overdue tasks are in red, and completed tasks, marked with a date in the past, are green. This visual aid helps you immediately focus on the most pressing tasks.

Conditional Formatting with date ranges is a versatile feature that can be tailored to fit various scenarios. Whether you're managing a team, tracking investments, or organizing events, mastering this tool can significantly enhance your productivity and data management capabilities.
