Compare Dates and Time

This example shows how to compare datetime and duration arrays. You can perform

an element-by-element comparison of values in two datetime arrays or two duration

arrays using relational operators, such as > and <.

Compare Datetime Arrays

Compare two datetime arrays. The arrays must be the same size or one can be a scalar.

A = datetime(2013,07,26) + calyears(0:2:6)

A = 1x4 datetime array

26-Jul-2013 26-Jul-2015 26-Jul-2017 26-Jul-2019

B = datetime(2014,06,01)

B = datetime

01-Jun-2014

A < B

ans = 1x4 logical array

1 0 0 0

The < operator returns logical 1 (true) where a datetime in A occurs before a datetime in

B.

Compare a datetime array to text representing a date.

A >= 'September 26, 2014'

ans = 1x4 logical array

0 1 1 1

Comparisons of datetime arrays account for the time zone information of each array.

Compare September 1, 2014 at 4:00 p.m. in Los Angeles with 5:00 p.m. on the same day

in New York.
