I asked what version of shell you're using, but you didn't provide an answer to that question. With a recent Korn shell, such as version 93u+, (which may be installed as ksh93 on AIX 7.1) you could try a simplified version of:
which if invoked with the operands FILE_NAME_20180410, FILE_NAME_20180413, and FILE_NAME_20180409 produces the output:

Hi, I have been trying just about every unix command to come up with yesterday's date (today's date - 1). I have seen all of the help on this forum, and none of it seems to work for me here.

curl_getdate
curl_getdate(3) libcurl Manual curl_getdate(3)NAME
curl_getdate - Convert an date in a ASCII string to number of seconds since January 1, 1970
SYNOPSIS
#include <curl/curl.h>
time_t curl_getdate(char *datestring, time_t *now");
DESCRIPTION
This function returns the number of seconds since January 1st 1970, for the date and time that the datestring parameter specifies. The now
parameter is there and should hold the current time to allow the datestring to specify relative dates/times. Read further in the date
string parser section below.
PARSING DATES AND TIMES
A "date" is a string, possibly empty, containing many items separated by whitespace. The whitespace may be omitted when no ambiguity
arises. The empty string means the beginning of today (i.e., midnight). Order of the items is immaterial. A date string may contain many
flavors of items:
calendar date items
This can be specified in a number of different ways. Including 1970-09-17, 70-9-17, 70-09-17, 9/17/72, 24 September 1972, 24 Sept
72, 24 Sep 72, Sep 24, 1972, 24-sep-72, 24sep72. The year can also be omitted, for example: 9/17 or "sep 17".
time of the day items
This string specifies the time on a given day. Syntax supported includes: 18:19:0, 18:19, 6:19pm, 18:19-0500 (for specifying the
time zone as well).
time zone items
Specifies international time zone. There are a few acronyms supported, but in general you should instead use the specific realtive
time compared to UTC. Supported formats include: -1200, MST, +0100.
day of the week items
Specifies a day of the week. If this is mentioned alone it means that day of the week in the future.
Days of the week may be spelled out in full: `Sunday', `Monday', etc or they may be abbreviated to their first three letters,
optionally followed by a period. The special abbreviations `Tues' for `Tuesday', `Wednes' for `Wednesday' and `Thur' or `Thurs'
for `Thursday' are also allowed.
A number may precede a day of the week item to move forward supplementary weeks. It is best used in expression like `third mon-
day'. In this context, `last DAY' or `next DAY' is also acceptable; they move one week before or after the day that DAY by itself
would represent.
relative items
A relative item adjusts a date (or the current date if none) forward or backward. Example syntax includes: "1 year", "1 year ago",
"2 days", "4 weeks".
The string `tomorrow' is worth one day in the future (equivalent to `day'), the string `yesterday' is worth one day in the past
(equivalent to `day ago').
pure numbers
If the decimal number is of the form YYYYMMDD and no other calendar date item appears before it in the date string, then YYYY is
read as the year, MM as the month number and DD as the day of the month, for the specified calendar date.
RETURN VALUE
This function returns zero when it fails to parse the date string. Otherwise it returns the number of seconds as described.
