Fechas y horas
Los tipos de datos de fecha y hora datetime
, duration
y calendarDuration
admiten cálculos eficientes, comparaciones y visualizaciones con formato de fechas y horas. Trabaje con estos arreglos de la misma forma que trabaja con los arreglos numéricos. Puede agregar, sustraer, ordenar, comparar, concatenar y representar gráficamente valores de fecha y hora. También puede representar fechas y horas como arreglos numéricos o como texto. Para obtener más información, consulte Represent Dates and Times in MATLAB o vea Arreglos de fecha y hora.
Funciones
Temas
- Represent Dates and Times in MATLAB
Use
datetime
arrays to store date and time information. These arrays support arithmetic, sorting, comparisons, plotting, and formatted display. - Compare Dates and Time
You can perform an element-by-element comparison of values in two
datetime
arrays or twoduration
arrays using relational operators, such as>
and<
. - Set Date and Time Display Format
The
Format
property ondatetime
,duration
, andcalendarDuration
arrays controls the display of values in each array. You can change the value of this property. Changing theFormat
property does not change the values in the array, only their display. - Specify Time Zones
When you create a datetime, it is unzoned by default. If you work with datetime values from multiple time zones or need to account for daylight saving time, you might need to specify a time zone.
- Share Code and Data Across Locales
Follow these best practices when sharing code that handles dates and time with MATLAB® users in other locales. Write and read dates from other locals.
- Core Functions Supporting Date and Time Arrays
Many functions in MATLAB operate on date and time arrays in much the same way that they operate on other arrays.

Carryover in Date Vectors and Strings
If an element falls outside the conventional range, MATLAB adjusts both that date vector element and the previous element.
Converting Date Vector Returns Unexpected Output
Because a date vector is a 1-by-6 vector of numbers, datestr
might interpret your input date vectors as vectors of serial date numbers—or interpret
serial date numbers as date vectors—and return unexpected output.
