## Configure Flow to Only Run on the Last Monday of the Month

Hi,

I am looking to add a condition to one of my existing flows to only run if an email arrives on the last Monday of the month.  This should look at the date in the Eastern time zone, if that helps.  As I mentioned, I already have a flow to create my attachments in SharePoint, so that part is done.

Any assistance is greatly appreciated!

Hi @ScottR-MT,

I can't think of a suitable Expression here to directly determine whether the current mail receiving date is the last Monday of this month.

However, consider using a combination of Condition and Expression to determine if the current date is the expected one, and if so, execute the following action.

• First determine if Received Time is Monday, and if so, perform the following judgment.
• Then use ticks() function to convert the last day of the month and Received Time into numbers, and you can see what ticks() function does.
• Use div() function to get the difference between the two dates, divide by 864000000000, and get a difference of a few days between the two dates.
• If the difference is less than or equals to 7, then Received Time of this message is the last Monday of the month.

Expression：

Condition:

`dayOfWeek(triggerBody()?['DateTimeReceived'])`

lastDay:

`ticks(formatDateTime(adddays(concat(add(int(formatDateTime(utcNow(), 'yyyy')),if(equals(formatDateTime(utcNow(), 'MM'), '12'), 1, 0) ),'-',add(int(formatDateTime(utcNow(), 'MM')),if(equals(formatDateTime(utcNow(), 'MM'), '12'), -11, 1) ),'-01T08:00Z'),-1),'yyyy-MM-ddTHH:mm'))`

`ticks(triggerBody()?['DateTimeReceived'])`

dayDiff:

`div(sub(outputs('lastDay'),outputs('ReceivedTime')),864000000000)`

Condition 2:

`div(sub(outputs('lastDay'),outputs('ReceivedTime')),864000000000)`

You could consider testing this Flow on Monday.
