datestr function Unrecognized month format error

Hello :) could you help me with that error below?

"Error using matlab.internal.datetime.cnv2icudf (line 99) Unrecognized month format. Format: mmmmm dd, yyyy HH:MM:SS.FFF AM."

Those are my codes;

clc; clear; close all;

monday=datestr(now,'mmmmm dd, yyyy HH:MM:SS.FFF AM')

Answer 1

you have 5 m for the month field but datestr only permits up to 4 m

We highly recommend using datetime in place of datestr, now, datenum, etc.

You can get a datetime version of the same value using datetime('now') and convert it to a text representation using the string function.

e.g.

dt = datetime('now','Format','MMMM dd, yyyy hh:mm:ss.SSS a')

dt = datetime
   July 14, 2021 05:07:08.084 PM

txt = string(dt)

txt = "July 14, 2021 05:07:08.084 PM"
