Dont you just love it this year? With the first day of counting ספירה falling on a Sunday, it is so easy to work out what day of ספירה it is. Today (sunday) was 4 weeks and ONE day. Monday is 4 weeks and TWO days. The days correspond with the day of the week, finishing each week on a שבת as the complete week.
So the pasuk fits in exactly in the literal sense as we count 7 weeks, finishing each on a שבת, until the end of the 7th שבת we count 50 days...
שבע שבתות תמימות תהיינה עד ממחרת השבת השביעית תספרו חמשים יום
