Odd Behavior from Date.strptime()-CodePudding

I'm doing a date conversion using strptime and it is normalizing my data to always have 2020 as the year and I'm not sure why. Specifically:

value = "2015/03/21"
value2 = Date.strptime(value, '%m/%d/%y')

produces a result where value2 = "2020-03-21" How do I get Date.strptime() to appropriately reflect the year?

CodePudding user response：

In value year is first, month is second. You want to create date object from string, so to correctly parse you should use correct order:

value = "2015/03/21"
value2 = Date.strptime(value, '%Y/%m/%d')
 => Sat, 21 Mar 2015

CodePudding user response：

The second argument of strptime is the input format in which the date is provided not the expected output format. Therefore change it to:

value = "2015/03/21"
value2 = Date.strptime(value, '%Y/%m/%d')
#=> #<Date: 2015-03-21 ((2457103j,0s,0n), 0s,2299161j)>
