Q4 refers to the fourth and final three-month period of a company's fiscal or calendar year, running from October 1 to December 31 for most businesses. It is a critical "make-or-break" period used to finalize annual revenue goals, wrap up financial activities, and prepare for year-end audits, frequently coinciding with the holiday shopping season.
The traditional calendar quarters that make up the year are:
Dates for Q1: January 1 – March 31. Dates for Q2: April 1 – June 3. Dates for Q3: July 1 – September 30. Dates for Q4: October 1 – December 31.
The standard calendar quarters that make up the year are as follows: January, February, and March (Q1) April, May, and June (Q2) July, August, and September (Q3) October, November, and December (Q4)
A quarterly event happens four times a year, at intervals of three months.
Q2 2025 means the second quarter in 2025, a calendar quarter, starting from April 1 and running through to June 30, 2025.
Historically, the fourth quarter of the year, known as Q4, comprising October, November, and December, more often than not delivers the best stock market returns of any given year.
Q1 is acronym that stands for the first quarter of the fiscal calendar or calendar year. For example, if the company has a calendar year that ends December 31st, then Q1 would be the financial results for January 1st to March 31st.
Quarterly payments happen every 3 months, not 4, because a quarter of a year is three months (12 months / 4 quarters = 3 months). For taxes, this means payments are made four times a year, typically around April 15, June 15, September 15, and January 15 of the next year, covering income from the preceding three-month period.
This period is the last chance to hit annual goals and capitalize on holiday sales, which account for approximately 19% of total retail sales each year, according to the National Retail Federation. For local businesses operating on tight budgets, maximizing Q4 opportunities is especially important.
Fourth Quarter or 4Q means the 3-month period of October, November and December.
Q4 is the last quarter of the fiscal year for companies. Most follow the calendar year, which means the fourth quarter starts Oct. 1 and ends Dec. 31. Some companies have fiscal years that follow dates that differ from the calendar year.

The "Rule of 90" in stocks most commonly refers to Warren Buffett's advice for his wife's inheritance: 90% in a low-cost S&P 500 index fund for growth and 10% in short-term government bonds for stability, designed for long-term investors.
