How to Parse Datetime-String with Am/Pm Marker

Unable to parse DateTime-string with AM/PM marker

One possibility is that your default Locale has different symbols for AM/PM. When constructing a date format you should always supply a Locale unless you really want to use the system's default Locale, e.g.:

SimpleDateFormat sdf = new SimpleDateFormat("M/d/yy h:mm:ss a", Locale.US)

Java - parse date with AM/PM next to seconds (no space)

with AM/PM you want 12 hours hh instead of 24 hours HH.

hh:mm:ss''a

As k/K/h/H influence a too, now everything might work with ssa.

If ssa is still problematic (seemingly a bug), try separating the letters by an empty literal string (single quotes).

The following works:

hh:mm:ssa

Parsing date and AM/PM using java 8 DateTime API

You can set the default values for unavailable fields via DateTimeFormatterBuilder.parseDefaulting:

DateTimeFormatter formatter = new DateTimeFormatterBuilder()
    .appendPattern("dd/MM/yyyy a")
    .parseDefaulting(ChronoField.HOUR_OF_AMPM, 0) // this is required
    .parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0) // optional, but you can set other value
    .parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0) // optional as well
    .toFormatter();
System.out.println(LocalDateTime.parse("17/02/2015 PM", formatter)); // 2015-02-17T12:00
System.out.println(LocalDateTime.parse("17/02/2015 AM", formatter)); // 2015-02-17T00:00

How do I change 'AM' to 'PM' in a Date Object JAVA

In Line:

SimpleDateFormat formatter6=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

The hh makes sure that hours are parsed as AM/PM values b/w 1-12. To get the desired result, you can use HH marker which parses hour values between 0-23. So, the code should be:

SimpleDateFormat formatter6=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

Display current time in 12 hour format with AM/PM

Easiest way to get it by using date pattern - h:mm a, where

h - Hour in am/pm (1-12)
m - Minute in hour
a - Am/pm marker

Code snippet :

DateFormat dateFormat = new SimpleDateFormat("hh:mm a");

Convert time to am/pm flutter

You can use the intl library https://pub.dev/packages/intl
and format your DateTime

 DateFormat.yMEd().add_jms().format(DateTime.now());

Output:

'Thu, 5/23/2013 10:21:47 AM'

Java Date TIME Format AM/PM Configuration

You can check this code you have to pass the am/pm part too with the date string value as your format is expecting that.

//String date = "11/06/2020 04:14:20";
String date = "11/06/2020 04:14:20 am";
DateFormat df = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss a");

Unable to parse AM/PM using SimpleDateFormat

Wait a second. The error says 12:34 is unparseable, not 12:34 AM. In that case, your input method is reading the first word up to whitespace and ignoring the "AM" part of your entry. Correct your input method so that it reads the entire input stream/string, and then it should parse correctly.
