Introduction

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

The `DATE`

function gives "the sequential serial number that represents a particular date. Use it when you have to take three different values and merge them to form a date," according to Excel's documentation.

The `DATE`

function has the following syntax:

`1=DATE(YEAR, MONTH, DAY)`

To understand this function, 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 | ? |

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 a date that is available as text to a serial number that will be recognized as a date by Excel," according to Excel's documentation.

The `DATEVALUE`

function has the following syntax:

`1=DATEVALUE(date_in_the_text_format)`

To implement the `DATEVALUE`

function , 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 which ranges from 1-31," according to Excel's documentation.

The `DAY`

function has the following syntax:

`1=DAY(date_serial_number_recognized_by_Excel)`

To implement the `DAY`

function, consider the example given in `DATEVALUE`

function section 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 | ? |

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`

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 **END_DATE** and **START_DATE**. The updated result in the **DAY** column is given below:

A | B | C | D |
