Datetime Patterns for Formatting and Parsing

There are several common scenarios for datetime usage in Spark:

Spark uses pattern letters in the following table for date and timestamp parsing and formatting:

Symbol Meaning Presentation Examples
G era text AD; Anno Domini
y year year 2020; 20
D day-of-year number(3) 189
M/L month-of-year month 7; 07; Jul; July
d day-of-month number(3) 28
Q/q quarter-of-year number/text 3; 03; Q3; 3rd quarter
E day-of-week text Tue; Tuesday
F aligned day of week in month number(1) 3
a am-pm-of-day am-pm PM
h clock-hour-of-am-pm (1-12) number(2) 12
K hour-of-am-pm (0-11) number(2) 0
k clock-hour-of-day (1-24) number(2) 0
H hour-of-day (0-23) number(2) 0
m minute-of-hour number(2) 30
s second-of-minute number(2) 55
S fraction-of-second fraction 978
V time-zone ID zone-id America/Los_Angeles; Z; -08:30
z time-zone name zone-name Pacific Standard Time; PST
O localized zone-offset offset-O GMT+8; GMT+08:00; UTC-08:00;
X zone-offset ‘Z’ for zero offset-X Z; -08; -0830; -08:30; -083015; -08:30:15;
x zone-offset offset-x +0000; -08; -0830; -08:30; -083015; -08:30:15;
Z zone-offset offset-Z +0000; -0800; -08:00;
escape for text delimiter  
’‘ single quote literal
[ optional section start    
] optional section end    

The count of pattern letters determines the format.
