Fiscal Quarter Conventions
Q1 of a non-calendar fiscal year is not the same as Q1 of the calendar year. Here is what each quarter means.
Calendar quarters versus fiscal quarters
Calendar Q1 is January–March. Fiscal Q1 is the first three months of the fiscal year, regardless of where those months fall in the calendar. For a US federal entity, fiscal Q1 is October–December. For a UK Self Assessment year, fiscal Q1 is April–June.
When reading a press release or earnings transcript, check which convention the speaker is using. Public-company earnings calls almost always use fiscal quarters; macroeconomic commentary almost always uses calendar quarters. Conflating the two produces six-month errors in trend analysis.
What each fiscal quarter typically holds
Q1 is the opening quarter. Budgets that cleared the year-end review are now operative; focus is on translating planned spend into committed spend.
Q2 is the first reforecast quarter. Variance from the year-end budget becomes statistically meaningful, mid-year reviews are scheduled at the close of FM6.
Q3 is when annual targets become defensible or not. Pipeline that matured in Q1–Q2 lands as recognised revenue.
Q4 is the close-and-handoff quarter. External audit walkthroughs begin, accruals get scrubbed, and the next fiscal year's budget is being signed in parallel.
Worked example: a July–June fiscal year
Australia's fiscal year runs July 1 to June 30. Q1 is July–September, Q2 is October–December, Q3 is January–March, Q4 is April–June. A Q1 reforecast on this calendar lands in October, when the rest of the world is thinking about calendar Q4. A Q4 close on this calendar happens in July, while northern-hemisphere companies on a calendar fiscal year are mid-Q3 of the next planning year.
When financial press covers cross-border deals, "Q3 results" without a fiscal-year prefix is ambiguous. Always read the year-end disclosure on the issuer's investor-relations page to confirm which calendar months they are referring to.
How we display quarters
On every quarterly template page on FiscalGrid we render the three constituent monthly grids side by side, in fiscal-month order. The header strip shows the FM range (e.g. "FM4–FM6"), the calendar months it covers, and a one-paragraph summary of what the quarter typically means in the planning cycle. This avoids the constant mental translation between calendar quarters and fiscal quarters.
When choosing a quarter to review, prefer the FM-range label over the calendar months. "Q2 FY26" is a stable identifier; "the quarter ending December 2025" depends on which company you are talking about.
