Extract or Assign Date and Time Components of

Datetime Array

This example shows two ways to extract date and time components from existing

datetime arrays: accessing the array properties or calling a function. Then, the example

shows how to modify the date and time components by modifying the array properties.

Access Properties to Retrieve Date and Time Component

Create a datetime array.

t = datetime('now') + calyears(0:2) + calmonths(0:2) + hours(20:20:60)

t = 1x3 datetime array

13-Apr-2019 23:12:56 14-May-2020 19:12:56 15-Jun-2021 15:12:56

Get the year values of each datetime in the array. Use dot notation to access the Year

property of t.

t_years = t.Year

t_years = 1×3

2019 2020 2021

The output, t_years, is a numeric array.

Get the month values of each datetime in t by accessing the Month property.

t_months = t.Month

t_months = 1×3

4 5 6

You can retrieve the day, hour, minute, and second components of each datetime in t by

accessing the Hour, Minute, and Second properties, respectively.
