addDays Calcuation

I am working on a New Hire flow.  When a form is submitted, it creates the flow process to add tasks to the Teams Planner.

Currently, when a new employee is entered, the Start Date is subtracted by 9 days in the flow as to when to create the account.  But if the new hire request is created and the employee starts in say 3 days instead of 9, the task shows past due.

 

Is there a way to make some calcuation based on the start date that the date in the planner is, say todays date versus a future date?

All you need to do is have the same expression for each different task, but you only have to change the number of days in the expression where it currently has 9.

 

This is the original checking for 9 days.

addDays(variables('EmpStartDate'),mul(-1,if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(9)),int(9),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000))))

 

This is the same except checking for 5 days:

addDays(variables('EmpStartDate'),mul(-1,if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(5)),int(5),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000))))

 

All that was changed was the number 9 to 5.

 

Does that help? Or is there something I am not understanding that needs to be recognized?

@billf24 

Could you add a condition that says if the date calculated is less than today, use today.  Otherwise use the date calculated.

You can us a dateDifference expression to find the difference in days. If you go this way, let me know and I will provide an expression for you.  

 

If you need an example, please let me know.

Yes it can be done.

I'm going to make the expression assuming you want it to be -9 days if the Employee Start Date is more than 9 days away. If the employee start date and current date are less than 9 days difference, it will return the number of days and subtract that from the employee start date.

 

This is going to be a long expression, so I'm going to build it in steps. In my example, I used variables as place holders for where you will put the current date and employee start date.

 

My variables:

variables('EmpStartDate') = the employee start date you can replace with the form response

variables('ExampleCurrentDate') = the current date you can use the form submission time or utcNow()

 

A. First part of expression to get days between current date and employee start date:

div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000)

 

B. Second part of expression is to check if the amount of days difference is greater than or equals 9:

greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(9))

 

C. Third part of the expression is an IF statement. If the days between is greater or equals 9 then return 9, else return the day difference between current date and employee start date:

if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(9)),int(9),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000))

 

D. Fourth part of the expression is to convert the result to a negative number by multiplying by -1.

mul(-1,if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(9)),int(9),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000)))

 

E. Full Expression - this adds a fifth part of the expression is the addDays to the employee start date that will be used as the planner date:

addDays(variables('EmpStartDate'),mul(-1,if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(9)),int(9),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000))))

 

The expression in part E is the fully combined expression that can be used. 

 

Here is an example where I have the EmpStartDate as 2023-12-18 and the ExampleCurrentDate as 2023-12-01. Since these are 18 days apart we want to return a planner date that is only 9 days away from the employee start date which would be 2023-12-09.

Example of dates greater than 9 days apart. EmpStartDate December 18, 2023 and the ExampleCurrentDate is December 1, 2023Example of dates greater than 9 days apart. EmpStartDate December 18, 2023 and the ExampleCurrentDate is December 1, 2023Result example dates greater than 9 days apart. This returns a date that is only 9 days from the EmpStartDate which is December 9, 2023Result example dates greater than 9 days apart. This returns a date that is only 9 days from the EmpStartDate which is December 9, 2023

 

Here is an example where I have the EmpStartDate as 2023-12-18 and the ExampleCurrentDate as 2023-12-14. Since these are 4 days apart we want to return a planner date that is only 4 days away from the employee start date which would be 2023-12-14.

Employee Start Date Less than 9 daysEmployee Start Date Less than 9 daysResults Employee Start Date less than 9 daysResults Employee Start Date less than 9 days

 

 

I hope this example helps. I used the Designer Classic View instead of the Co-Pilot view. You can find all of the functions used in the expression here at Reference Guide for Expression Functions.

if() - If

mul() - Multiply

div() - divide

sub() - subtract

int() - convert to integer number

 

I also used the ticks() function which is explained in depth on a post I made here Using Ticks to find time between two dates.

Thank you for the feedback, as this almost works for what I am looking for.  What I mean by almost is that it does exactly what you provided me.

The exception is there are over a dozen tasks that are created with each having a different due date then just the start date.

 

I use the Create a Task squence and put the addDate in the Due Date Time field.  So when a new hire is entered into Flow, there are items that need to be done immediately, so may be 3 days before they start others could be the day they start or 14 days after they start.

I know this is a little more complicated and I appreciated your time and effort.

All you need to do is have the same expression for each different task, but you only have to change the number of days in the expression where it currently has 9.

 

This is the original checking for 9 days.

addDays(variables('EmpStartDate'),mul(-1,if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(9)),int(9),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000))))

 

This is the same except checking for 5 days:

addDays(variables('EmpStartDate'),mul(-1,if(greaterOrEquals(div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000),int(5)),int(5),div(sub(ticks(variables('EmpStartDate')),ticks(variables('ExampleCurrentDate'))),864000000000))))

 

All that was changed was the number 9 to 5.

 

Does that help? Or is there something I am not understanding that needs to be recognized? 

Yes, I thought and tried that right after I sent the first reply.

 

Thanks for the assistance.
