Redford made the announcement on Twitter.
The spending document is expected to be a key battleground in the upcoming provincial election, which by law must be held in March, April or May.
The Wildrose party has said the budget will show if Redford is a true fiscal conservative or a spender like her predecessor, Ed Stelmach.
The budget is expected to run a fifth consecutive deficit, though Redford has promised to balance spending with revenues by 2014.
The province is on track to run a $3.1-billion deficit this fiscal year.
