Visual Demo (For contributors especially)

N/A - This PR contains documentation and unit tests only, no UI changes.

Mandatory Tasks (DO NOT REMOVE)

• I have self-reviewed the code (A decent size PR without self-review might be rejected).
• I have updated the developer docs in /docs if this PR makes changes that would require a documentation change. If N/A, write N/A here and check the checkbox. N/A - This adds QA documentation and unit tests
• I confirm automated tests are in place that prove my fix is effective or that my feature works. 73 new unit tests added, all passing

How should this be tested?

Run the unit tests:

TZ=UTC yarn vitest run

Review should focus on:

• Verify new unit tests follow existing Cal.com patterns (vitest, describe/it blocks)
• Check test coverage report accurately reflects execution results
• Ensure traceability matrix correctly links BRD requirements to tests
• Verify BRD requirements accurately reflect Cal.com functionality

Checklist

• I have read the contributing guide
• My code follows the style guidelines of this project
• I have checked if my changes generate no new warnings

Human Review Checklist

• Unit tests follow existing Cal.com vitest patterns and conventions
• Test coverage report counts (73 new tests, 4703 total passed) match actual execution
• Traceability matrix requirement IDs (BRD-AUTH-xxx, BRD-EVT-xxx, etc.) align with BRD sections
• convertToNewDurationType test for hours→days uses multiplication (matches source behavior, but verify this is intended)
• BRD business requirements and context paragraphs align with actual product behavior
• Test case summary counts (105 total) match actual test cases in the document

🟡 Test encodes incorrect hours-to-days conversion logic (pre-existing source bug)

The test at lines 35-38 asserts that converting 1 hour to days yields 24, and 2 hours to days yields 48. This is mathematically wrong: 1 hour = 1/24 of a day ≈ 0.042 days (ceil → 1 day), not 24 days.

Root Cause: Source code multiplies instead of dividing for hours→days

The source code at packages/lib/convertToNewDurationType.ts:19 defines:

hours_days: () => prevValue * HOURS_IN_DAY,

This multiplies hours by 24 to get "days", but the correct conversion is to divide hours by 24 (or equivalently, convert hours to minutes first, then divide by minutes-per-day):

hours_days: () => prevValue / HOURS_IN_DAY,

For comparison, the reverse conversion days_hours at line 21 also uses prevValue * HOURS_IN_DAY, which IS correct (1 day = 24 hours). The asymmetry reveals the bug: hours_days and days_hours should be inverses of each other, but both multiply.

The test documents this buggy behavior rather than the correct mathematical conversion. In practice, the hours_days path is not exercised by the current UI code (which always converts through "minutes" as the canonical unit), so the bug has no visible impact today. However, the test cements incorrect behavior that would cause problems if the hours→days path is ever used directly.

Impact: If convertToNewDurationType("hours", "days", ...) is ever called directly, it will return wildly incorrect values (e.g., 24 days instead of ~0.042 days for 1 hour input).

Prompt for agents

Fix the pre-existing bug in packages/lib/convertToNewDurationType.ts at line 19. The hours_days conversion currently multiplies by HOURS_IN_DAY (24) but should divide by it. Change:

  hours_days: () => prevValue * HOURS_IN_DAY,

to:

  hours_days: () => prevValue / HOURS_IN_DAY,

Then update the test in packages/lib/convertToNewDurationType.test.ts lines 35-38 to reflect the correct behavior:

  it("should convert hours to days", () => {
    expect(convertToNewDurationType("hours", "days", 24)).toBe(1);
    expect(convertToNewDurationType("hours", "days", 48)).toBe(2);
    expect(convertToNewDurationType("hours", "days", 1)).toBe(1); // ceil(1/24) = 1
  });

Verify that no existing callers rely on the current (incorrect) behavior by searching for convertToNewDurationType usage with "hours" and "days" arguments.
