days - Duration in days - MATLAB (original) (raw)

Main Content

Syntax

D = days([X](#bugc82y-1-X)) returns an array of fixed-length days equivalent to the values in the input array.

If X is a numeric array, thenD is a duration array in units of fixed-length days. A fixed-length day is equal to 24 hours.
If X is a duration array, then D is a double array with each element equal to the number of fixed-length (24-hour) days in the corresponding element of X.

The days function converts betweenduration and double values. To display a duration in units of days, set its Format property to'd'.

X = magic(2); D = days(X)

D = 2×2 duration 1 day 3 days 4 days 2 days

Add each number of fixed-length days to the current date and time.

t = 2×2 datetime 02-Feb-2025 08:52:21 04-Feb-2025 08:52:21 05-Feb-2025 08:52:21 03-Feb-2025 08:52:21

Create a duration array.

X = hours(23:20:95) + minutes(45)

X = 1×4 duration 23.75 hr 43.75 hr 63.75 hr 83.75 hr

Convert each duration in X to a number of days.

D = 1×4

0.9896    1.8229    2.6562    3.4896

Input array, specified as a numeric array, duration array, or logical array.

days creates fixed-length (24 hour) days. To create days that account for Daylight Saving Time shifts when used in calendar calculations, use the caldays function.

Thedays function fully supports tall arrays. For more information, see Tall Arrays.
