No, the Medicare 100-day limit for skilled nursing facility (SNF) care doesn't reset with the calendar year; it resets with each new "benefit period," which starts after you've been out of a hospital or SNF for 60 consecutive days, allowing for new deductibles and coinsurance to apply. You can have multiple benefit periods, and thus potentially use the 100 days more than once, within the same calendar year if you meet the 60-day gap requirement between periods.

A benefit period begins the day you're admitted as an inpatient in a hospital or SNF.
