Here is a typical formula for calculating strength based on time for "normal" concrete. You have to know the design or expected f'c. t is time in days since the concrete was cast. f'ci= f'c*(t/(4.00+0.85t)) If you don't know the f'c, back into it using the 7-day break value. Then use that f'c value to calculate your 28-day strength.
