In this guide, you will learn how to work with time and date functions in Microsoft Excel 2019. There are various time and date functions which are present in the Excel 2019 version, as mentioned below:

- DATE
- DATEVALUE
- DAY
- DAYS
- DAYS360
- EDATE
- EOMONTH
- HOUR
- ISOWEEKNUM
- MINUTE
- MONTH

In this section, you will learn about each of these time and date functions through various scenarios.

The `DATE`

function gives the sequential serial number that represents a particular date. We use the `DATE`

function when we take three different values and merge them to form a date.

The `DATE`

function has the following syntax:

`1`

`=DATE(YEAR, MONTH, DAY)`

The `DATE`

function has three arguments as `YEAR`

, `MONTH`

and `DAY`

. All of the three arguments in the function are **required**.

DAY The

`DAY`

argument represents day of the month from 1 - 31. If you use a value more than 31 for this argument, it will be added to the first day of the month given as the second argument. For instance, if you use 32 in the third argumentin excel, it will give output as`=DATE(2005, 11, 32)`

.`02-12-2005`

MONTH The

`MONTH`

argument represents the month of the year from 1 - 12. If you use a value more than 12 for this argument, it will be added to the first month of the year given as the first argument. For instance, if you use 16 in second argumentin excel, it will give output as`=DATE(2005, 16, 2)`

.`02-04-2006`

YEAR The

`YEAR`

argument can contain one to four digits. It is always better to use four digits as the argument in the function to avoid any kind of confusion, as Microsoft Excel for Windows uses the 1900 date system by default. So, if you use one digit in first argumentin Excel, it will give output as`=DATE(1, 11, 2)`

. So, it is always a good practice to use four digits in the first argument.`02-11-1901`

Let us consider a scenario where you can learn how to implement the `DATE`

function in Excel. Consider the example given below.

A | B | C | D | E |
---|---|---|---|---|

SR. NO. | YEAR | MONTH | DAY | RESULT |

1 | 2019 | 08 | 19 | ? |

2 | 2019 | 11 | 5 | ? |

3 | 2019 | 10 | 5 | ? |

Now, let us put the formula ** =DATE(B1, C1, D1)** in cell

`E1`

and then apply it in subsequent rows. The result will be updated as shown below:A | B | C | D | E |
---|---|---|---|---|

SR. NO. | YEAR | MONTH | DAY | RESULT |

1 | 2019 | 08 | 19 | 19-08-2019 |

2 | 2019 | 11 | 5 | 05-11-2019 |

3 | 2019 | 10 | 5 | 05-10-2019 |

The `DATEVALUE`

function is used to convert date that is available as text to a serial number that will be recognized as a date by Excel.

The `DATEVALUE`

function has the following syntax:

`1`

`=DATEVALUE(DATE_TEXT)`

`DATE_TEXT`

is a **required** argument in the `DATEVALUE`

function.
Let us consider a scenario where you can learn how to implement the `DATEVALUE`

function in Excel. Consider the example given below:

A | B | C |
---|---|---|

SR. NO. | DATE_TEXT | RESULT |

1 | "05-11-2019" | =DATEVALUE("05-11-2019") |

2 | "18-08-2019" | =DATEVALUE("18-08-2019") |

3 | "19-08-2019" | =DATEVALUE("19-08-2019") |

The result will be updated as shown below:

A | B | C |
---|---|---|

SR. NO. | DATE_TEXT | RESULT |

1 | "05-11-2019" | 43774 |

2 | "18-08-2019" | 43695 |

3 | "19-08-2019" | 43696 |

To avoid any possible error, right click on the cell containing `DATE_TEXT`

and select `Format Cells...`

-> `text`

under `Number`

tab -> `OK`

.

The `DAY`

function returns the day of the given date or serial number and it ranges from 1-31.
The `DAY`

function has the following syntax:

`1`

`=DAY(DATE/SERIAL NUMBER)`

Let us consider a scenario where you can learn how to implement the `DAY`

function in Excel. You can consider the example given in `DATEVALUE`

function and find the day of the serial number given as output in that example.

A | B | C | D |
---|---|---|---|

SR. NO. | DATE_TEXT | RESULT | DAY |

1 | "05-11-2019" | 43774 | ? |

2 | "18-08-2019" | 43695 | ? |

3 | "19-08-2019" | 43696 | ? |

Now, let us put the formula ** =DAY(C1)** in cell

`D1`

and then apply it in subsequent rows. The result will be updated as shown below:A | B | C | D |
---|---|---|---|

SR. NO. | DATE_TEXT | RESULT | DAY |

1 | "05-11-2019" | 43774 | 5 |

2 | "18-08-2019" | 43695 | 18 |

3 | "19-08-2019" | 43696 | 19 |

The `DAYS`

function is used to calculate the days between two given dates.
The `DAYS`

function has the following syntax:

`1`

`=DAYS(end_date, start_date)`

Let us consider a scenario where you can learn how to implement the `DAYS`

function in Excel. Consider the example given below:

2 | 05-11-2019 | 05-11-2018 | ? |

3 | 18-07-2019 | 18-06-2019 | ? |

Now, let us put the formula ** =DAYS(B1,C1)** in cell

`D1`

and then apply it in subsequent rows. It will calculate the days between the A | B | C | D |
---|---|---|---|

SR. NO. | END_DATE | START_DATE | DAY |

1 | 19-08-2019 | 18-08-2019 | 1 |

2 | 05-11-2019 | 05-11-2018 | 365 |

3 | 18-07-2019 | 18-06-2019 | 30 |

The `DAYS360`

function is used to calculate the number of days between two given dates which is based on a 360-day year (twelve 30-day months).
The `DAYS360`

function has the following syntax:

`1`

`=DAYS360(start_date,end_date,[method])`

Let us consider a scenario where you can learn how to implement the `DAYS360`

2 | 05-11-2019 | 05-11-2018 | ? |

3 | 18-07-2019 | 18-06-2019 | ? |

Now, let us put the formula ** =DAYS(C1,B1)** in cell

`D1`

and then apply it in subsequent rows. The third argument is optional; it is a logical value depending on the user’s choice to use the U.S. or European method for the calculation. It will calculate the days between the A | B | C | D |
---|---|---|---|

SR. NO. | END_DATE | START_DATE | DAY |

1 | 19-08-2019 | 18-08-2019 | 1 |

2 | 05-11-2019 | 05-11-2018 | 360 |

2 | 05-11-2019 | -1 | ? |

3 | 18-07-2019 | 2 | ? |

Now, let us put the formula ** =EDATE(B1,C1)** in cell

`D1`

and then apply it in subsequent rows. This function will return the date after adding the A | B | C | D |
---|---|---|---|

SR. NO. | DATE | MONTH | NEW_DATE |

1 | 19-08-2019 | 1 | 19-09-2019 |

2 | 05-11-2019 | -1 | 05-10-2019 |

3 | 18-07-2019 | 2 | 18-09-2019 |

If the output is serial number, right-click that cell value -> click on `Format Cells...`

-> choose the format of date you want.

The `EOMONTH`

function gives the last day of the month of the indicated number of months before or after the `start_date`

as the serial number.

The `EOMONTH`

function has the following syntax:

`1`

`=EOMONTH(start_date, months)`

Let us consider a scenario where you can learn how to implement the `EOMONTH`
