# Highlight dates that are weekends

If you want to use conditional formatting to highlight dates occur on weekends (i.e. Saturday or Sunday), you can use a simple formula based on the WEEKDAY function.

For example, if you have dates in the range C4:C10, and want to weekend dates, select the range C4:C10 and create a new conditional formatting rule that uses this formula:

*Note: it's important that CF formulas be entered relative to the "active cell" in the selection, which is assumed to be C5 in this case.*

Once you save the rule, you'll see all dates that are a Saturday or a Sunday highlighted by your rule.

### How this formula works

This formula uses the WEEKDAY function to test dates for either a Saturday or Sunday. When given a date, WEEKDAY returns a number 1-7, for each day of the week. In it's standard configuration, Saturday = 7 and Sunday = 1. By using the OR function, use WEEKDAY to test for either 1 or 7. If either is true, the formula will return TRUE and trigger the conditional formatting.

### Highlighting the entire row

If you want to highlight the entire row, apply the conditional formatting rule to all columns in the table and lock the date column:
