Workday Adjusted Date Logic

[BJohnson_79]

I am trying to create date logic that would identify the current year workday and return sales from that same workday in the prior year. With the holidays so far this year, the issue i'm getting is my returned data is off by 1 workday.

Hi  @BJohnson_79 ,

I created some data:

Table:

holiday table:

Here are the steps you can follow：

1. Create calculated column.

Test =
var _week=WEEKDAY('Table'[Date],2)
var _column=SELECTCOLUMNS('holiday table',"date",[Date])
return
IF(
  'Table'[Date] in _column ||   _week in {6,7},0,1)

Workday =
IF(
    [Test]=0,BLANK(),
RANKX(
    FILTER(ALL('Table'),
    YEAR('Table'[Date])=YEAR(EARLIER('Table'[Date]))&&[Test]=1),'Table'[Date],,ASC)
)

Current =
IF(
    YEAR('Table'[Date])= YEAR(TODAY()),
    "Currrent Year")

2. Create measure.

compare =
var _lastyear=
MAXX(
    FILTER(ALL('Table'),
    YEAR('Table'[Date])=YEAR(MAX('Table'[Date]))-1&&'Table'[Workday]=MAX('Table'[Workday])),[Date])
var _value=
SUMX(
    FILTER(ALL('Table'),'Table'[Date]=_lastyear),[Value])
return
IF(
    MAX('Table'[Test])=BLANK(),BLANK(),
MAX('Table'[Value])- _value)

3. Result:

Based on the calendar, data Jan1- Jan18 of 2024 13 workdays.  The same period last year had 12 workdays due to Jan2 being an observed holiday.  

I am trying to write an expression that would identify the current year workday number, and compare it to the same workday number in the previous year, despite the calendar day being different.

Is there any column you are maintaining to identify that pasrticular date as a Holiday ?

[BJohnson_79]

Yes, my date table contains workday data for current year and prior year

Hi @BJohnson_79 ,
While trying to undertstand your question, I am confused as to what result are you expecting if the current year has holiday and the prior year too ?
Should be taking day-1 ?
