YEAR, MONTH, DAY extraction in Google Sheets - Dashboard Guide

Dashboard Mode - YEAR, MONTH, DAY extraction

Dashboard Goal

Understand how to extract the year, month, and day from dates in a spreadsheet to analyze sales data by these time parts.

Sample Data

Date	Sales
2024-01-15	150
2024-02-20	200
2023-12-05	180
2024-01-30	220
2023-11-25	170
2024-02-10	210

Dashboard Components

• Year Column: Extract year from Date using =YEAR(A2). Shows the year for each sale.
• Month Column: Extract month number from Date using =MONTH(A2). Shows the month number (1-12).
• Day Column: Extract day number from Date using =DAY(A2). Shows the day of the month.
• Total Sales by Year: Sum sales grouped by year using =SUMIF(C$2:C$7, E2, B$2:B$7) where column C has the extracted years and column E has unique years.
• Total Sales by Month: Sum sales grouped by month using =SUMIF(D$2:D$7, G2, B$2:B$7) where column D has the extracted months and column G has unique months.

Interactivity

Filtering the data table by date or year updates the extracted columns and the total sales summaries automatically. Selecting a specific year or month filters the sales totals to that period.

Self Check

If you add a filter to show only sales from 2024, which components update?

• The extracted Year, Month, and Day columns show only 2024 dates.
• Total Sales by Year shows only 2024 total.
• Total Sales by Month updates to show sales totals for months in 2024.

Key Result

Dashboard shows how to extract year, month, and day from dates and summarize sales by these parts.

Practice

1. What does the YEAR function do in Google Sheets when applied to a date like 2024-06-15?

easy

A. It extracts the year part as a number, e.g., 2024.

B. It extracts the month part as a number, e.g., 6.

C. It extracts the day part as a number, e.g., 15.

D. It converts the date to text format.

Solution

1. Step 1: Understand the YEAR function

   The YEAR function extracts the year number from a date value.

2. Step 2: Apply YEAR to the date 2024-06-15

   Applying YEAR to 2024-06-15 returns 2024 as the year part.

3. Final Answer:

   It extracts the year part as a number, e.g., 2024. -> Option A

4. Quick Check:

   YEAR(DATE(2024,6,15)) = 2024 [OK]

Hint: YEAR extracts the year number from a date [OK]

Common Mistakes:

• Confusing YEAR with MONTH or DAY functions
• Expecting a text output instead of a number
• Using YEAR on a text string not recognized as a date

2. Which of the following is the correct syntax to extract the month from a date in cell A1 in Google Sheets?

easy

A. =MONTH{A1}

B. =MONTH[A1]

C. =MONTH(A1)

D. =MONTH A1

Solution

1. Step 1: Recall correct function syntax

   Functions in Google Sheets use parentheses () around arguments.

2. Step 2: Check each option

   Only =MONTH(A1) uses correct parentheses syntax: =MONTH(A1).

3. Final Answer:

   =MONTH(A1) -> Option C

4. Quick Check:

   Correct function syntax uses parentheses [OK]

Hint: Use parentheses () for function arguments [OK]

Common Mistakes:

• Using square brackets or curly braces instead of parentheses
• Omitting parentheses entirely
• Adding extra spaces inside function name

3. Given cell A1 contains the date 2023-12-25, what will the formula =DAY(A1) return?

medium

A. 12

B. 25

C. 2023

D. Error

Solution

1. Step 1: Understand the DAY function

   DAY extracts the day number from a date value.

2. Step 2: Apply DAY to 2023-12-25

   The day part of 2023-12-25 is 25, so DAY(A1) returns 25.

3. Final Answer:

   25 -> Option B

4. Quick Check:

   DAY(DATE(2023,12,25)) = 25 [OK]

Hint: DAY returns the day number from a date [OK]

Common Mistakes:

• Confusing day with month or year
• Expecting a text string instead of a number
• Using DAY on a non-date value

4. You wrote the formula =MONTH(A1 to extract the month from a date in cell A1, but it shows an error. What is the problem?

medium

A. MONTH function requires two arguments.

B. MONTH function cannot be used on dates.

C. Cell A1 is empty.

D. Missing closing parenthesis ")".

Solution

1. Step 1: Check formula syntax

   The formula =MONTH(A1 is missing the closing parenthesis ")".

2. Step 2: Understand function requirements

   MONTH requires one argument inside parentheses; missing ")" causes syntax error.

3. Final Answer:

   Missing closing parenthesis ")". -> Option D

4. Quick Check:

   Correct syntax =MONTH(A1) [OK]

Hint: Always close parentheses in formulas [OK]

Common Mistakes:

• Forgetting to close parentheses
• Assuming MONTH needs multiple arguments
• Ignoring error messages

5. You have a date in cell B2 as 2024-01-05. You want to create a formula that returns the date in the format "Day: 5, Month: 1, Year: 2024". Which formula will do this correctly?

hard

A. ="Day: " & DAY(B2) & ", Month: " & MONTH(B2) & ", Year: " & YEAR(B2)

B. =CONCATENATE("Day: ", DAY(B2), ", Month: ", MONTH(B2), ", Year: ", YEAR(B2))

C. =TEXT(B2, "Day: d, Month: m, Year: yyyy")

D. =DAY(B2) & "," & MONTH(B2) & "," & YEAR(B2)

Solution

1. Step 1: Understand the goal

   The formula must return text exactly like "Day: 5, Month: 1, Year: 2024" combining text and date parts.

2. Step 2: Check each option

   ="Day: " & DAY(B2) & ", Month: " & MONTH(B2) & ", Year: " & YEAR(B2) uses & to join text and functions correctly. =CONCATENATE("Day: ", DAY(B2), ", Month: ", MONTH(B2), ", Year: ", YEAR(B2)) also works but CONCATENATE is less common now. =TEXT(B2, "Day: d, Month: m, Year: yyyy") uses TEXT with wrong format string, so it won't produce the exact text. =DAY(B2) & "," & MONTH(B2) & "," & YEAR(B2) misses text labels.

3. Final Answer:

   ="Day: " & DAY(B2) & ", Month: " & MONTH(B2) & ", Year: " & YEAR(B2) -> Option A

4. Quick Check:

   Concatenate text and date parts with & [OK]

Hint: Use & to join text and date parts in formulas [OK]

Common Mistakes:

• Using TEXT with wrong format codes
• Forgetting to add text labels
• Using commas without text labels
