Conditional Formatting in Sharepoint List based on expiry date within 30 days

Hi MattBenson,

When I used the code provided, all I did was copy & paste it across, not really understanding the components.  After a little googling, I found that in my code (above), the number 2592000000 actually represents 30 days in milliseconds.

If I use my code and change that number to represent 6 months in milliseconds (15778800000), it will change my expiry date column to make anything that expires within the next 6 months orange and bold.

This is what I used to calculate the time - https://convertlive.com/u/convert/months/to/milliseconds#6

And this is the code I used, altered to allow for 6 months instead of 30 days. 

{
"$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
"elmType": "div",
"txtContent": "@currentField",
"style": {
"color": "=if(@currentField <= @now, 'crimson',if(@currentField <= @now + 15778800000 && @currentField > @now,'orange','black'))",
"font-weight": "=if(@currentField <= @now, 'bold',if(@currentField <= @now + 15778800000 && @currentField > @now,'bold','normal'))",
"font-size": "=if(@currentField <= @now, '14px',if(@currentField <= @now + 15778800000 && @currentField > @now,'14px','normal'))"
}
}

This will format any date in my 'Expiry Date' column as follows:

Expiry date before today is bold & crimson

Expiry date in the next 6 months is bold & orange

Expiry date more than 6 months from today is regular & black

I hope that helps.
