A3Pay bills
B32024-06-15
A4Doctor appointment
B42024-06-20
A5Meeting with team
B52024-06-25
A6Submit report
B62024-06-30
Formula Trace
=B2<TODAY()
Step 1: B2
Step 2: TODAY()
Step 3: 2024-06-10 < 2024-06-18
Cell Reference Map
    A               B
1 | Task            | Due Date  |
2 | Buy groceries   | 2024-06-10 |
3 | Pay bills       | 2024-06-15 |
4 | Doctor appointment | 2024-06-20 |
5 | Meeting with team | 2024-06-25 |
6 | Submit report   | 2024-06-30 |

Formula references cell B2 and uses TODAY() function.
The formula checks if the date in B2 is before today's date.
Result
    A               B           C
1 | Task            | Due Date  | Overdue? |
2 | Buy groceries   | 2024-06-10 | TRUE    |
3 | Pay bills       | 2024-06-15 | TRUE    |
4 | Doctor appointment | 2024-06-20 | FALSE   |
5 | Meeting with team | 2024-06-25 | FALSE   |
6 | Submit report   | 2024-06-30 | FALSE   |
Column C shows TRUE if the task is overdue (due date before today), FALSE otherwise.
Sheet Trace Quiz - 3 Questions
Test your understanding
What does the formula =B2<TODAY() check?
AIf the date in B2 is after today
BIf the date in B2 is equal to today
CIf the date in B2 is before today
DIf the date in B2 is empty
Key Result
Date-based formatting formulas compare a date cell with TODAY() to check if it is before or after the current date.

Practice

(1/5)
1. What does date-based formatting in Google Sheets primarily help you do?
easy
A. Highlight cells based on date conditions
B. Sort dates in ascending order
C. Convert text to dates automatically
D. Calculate the difference between two dates

Solution

  1. Step 1: Understand the purpose of date-based formatting

    Date-based formatting changes how cells look based on date rules, like coloring dates before or after today.

  2. Step 2: Compare with other options

    Sorting, converting, and calculating dates are different features, not formatting.

  3. Final Answer:

    Highlight cells based on date conditions -> Option A

  4. Quick Check:

    Date-based formatting = Highlight cells by date [OK]
Hint: Date formatting changes cell look based on dates [OK]
Common Mistakes:
  • Confusing formatting with sorting
  • Thinking it converts text to dates
  • Assuming it calculates date differences
2. Which formula is correct to use in conditional formatting to highlight dates before today?
easy
A. =DATE()
B. =TODAY()
C. =A1
D. =A1>NOW()

Solution

  1. Step 1: Identify the correct comparison for dates before today

    To highlight dates before today, the cell date (A1) must be less than TODAY(), so formula is =A1

  2. Step 2: Check other options for correctness

    A uses DATE() incorrectly without arguments; B (=TODAY()

  3. Final Answer:

    =A1<TODAY() -> Option C

  4. Quick Check:

    Use =A1<TODAY() to highlight past dates [OK]
Hint: Use =A1
Common Mistakes:
  • Using NOW() instead of TODAY()
  • Reversing comparison signs
  • Using DATE() without arguments
3. Given the formula =A2>=TODAY() in conditional formatting, what happens if A2 contains the date 2024-06-01 and today is 2024-05-30?
medium
A. The cell is not highlighted because 2024-06-01 is before today
B. The cell is highlighted because 2024-06-01 is after today
C. The formula causes an error
D. The cell is highlighted only if time is included

Solution

  1. Step 1: Compare the date in A2 with today's date

    A2 has 2024-06-01, which is after 2024-05-30 (today).

  2. Step 2: Evaluate the formula condition

    The formula checks if A2 is greater or equal to TODAY(), which is true, so the cell is highlighted.

  3. Final Answer:

    The cell is highlighted because 2024-06-01 is after today -> Option B

  4. Quick Check:

    =A2>=TODAY() is TRUE for future dates [OK]
Hint: Dates after or on today make =A2>=TODAY() TRUE [OK]
Common Mistakes:
  • Confusing before and after dates
  • Thinking formula causes error
  • Assuming time affects date comparison here
4. You want to highlight dates that are exactly 7 days from today using conditional formatting. Which formula has an error?
medium
A. =A1=TODAY()+"7 days"
B. =A1=TODAY()-7
C. =A1=TODAY()+7
D. =A1=EDATE(TODAY(),7)

Solution

  1. Step 1: Understand how to add days to TODAY()

    Adding 7 as a number to TODAY() works to get a date 7 days ahead.

  2. Step 2: Identify the error in =A1=TODAY()+"7 days"

    =A1=TODAY()+"7 days" adds a string "7 days" instead of a number, causing a formula error.

  3. Final Answer:

    =A1=TODAY()+"7 days" -> Option A

  4. Quick Check:

    Add numbers, not strings, to TODAY() [OK]
Hint: Add numbers, not text, to TODAY() for date math [OK]
Common Mistakes:
  • Adding text instead of numbers
  • Subtracting instead of adding days
  • Using wrong operators
5. You want to highlight all dates in column A that are within the next 3 days including today. Which conditional formatting custom formula should you use?
hard
A. =A1>TODAY()+3
B. =OR(A1>=TODAY(), A1<=TODAY()+3)
C. =A1
D. =AND(A1>=TODAY(), A1<=TODAY()+3)

Solution

  1. Step 1: Define the date range condition

    We want dates from today up to 3 days ahead, so A1 must be >= TODAY() and <= TODAY()+3.

  2. Step 2: Choose the correct logical function

    AND ensures both conditions are true simultaneously, so use =AND(A1>=TODAY(), A1<=TODAY()+3).

  3. Final Answer:

    =AND(A1>=TODAY(), A1<=TODAY()+3) -> Option D

  4. Quick Check:

    Use AND for date range between today and 3 days ahead [OK]
Hint: Use AND to check date is between two dates [OK]
Common Mistakes:
  • Using OR instead of AND
  • Checking only one side of the range
  • Using > or < incorrectly
