Hi and welcome @Semyon_Sushich!
I would add a formula field that monitors the status of the project and outputs
- if the project have been delivered.
 
- if today is before planned day of delivery and if so, how many days that are left.
 
- If today is after planned day of delivery and no delivery has been made and if so, how many days it’s overdue.
 
I like to add emojis to my status formulas, but they can easily be removed if you prefer not to use them.
You need 3 fields to achieve this:
- {planned date of delivery} = Date field
 
- {actual date of delivery} = Date field
 
- {formula field} = Formula field
 
In the formula field you add the following formula
IF({actual date of delivery},
	'✅ Delivered',
	IF({planned date of delivery}=BLANK(),
		'',
		IF(
			IS_BEFORE(
				TODAY(),
				{planned date of delivery}
			),
			'⏳ '&DATETIME_DIFF({planned date of delivery},TODAY(), 'days')&' day(-s) left to planned date of delivery',
			'🔴 '&DATETIME_DIFF(TODAY(),{planned date of delivery}, 'days')&' day(-s) overdue'
		)
	)
)
