Relative Time

The target is 2 days from now.

How it works

• Parsed the target and reference instants.
• Measured the signed difference and decomposed its magnitude with a fixed scale: 365-day years, 30-day months, 7-day weeks, then days, hours, minutes and seconds.
• Reported both the human-readable phrase and the exact numeric breakdown.

• The scale is fixed, not calendar-aware; use the Duration Calculator for a calendar breakdown.
• Swapping the target and reference flips the direction but keeps the magnitudes.

Methodology

1. Parse the target and reference as absolute instants; when no reference is supplied, read the current instant at runtime.
2. Measure the signed difference and decompose its magnitude by a fixed descending scale.
3. Return a short human-readable phrase, the direction, and the full numeric breakdown.

Time model

• Time source: an explicit reference supplied by the visitor.
• Timezone: Instants are absolute; a date-only input is read as UTC midnight and no timezone conversion is performed.
• Locale: Fixed English scale labels; no locale-specific formatting or pluralisation rules.
• Daylight saving: The span between absolute instants is DST-independent.
• Reference date: Optional. When omitted, the current instant is read from the visitor's environment; a supplied reference fixes the comparison. Examples always supply one.

Usage

1. Enter the target instant (or date).
2. Optionally enter a reference instant; leave it blank to compare with the current time.
3. Read the phrase, direction and numeric breakdown.

Examples

These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.

A future instant

{
  "target": "2026-01-01T00:00:00Z",
  "reference": "2025-12-30T00:00:00Z"
}

A past instant

{
  "target": "2026-01-01T00:00:00Z",
  "reference": "2026-01-03T06:00:00Z"
}

Across a leap day

{
  "target": "2024-03-01T00:00:00Z",
  "reference": "2024-02-28T00:00:00Z"
}

Limitations

Fixed scale versus calendar duration

Relative phrasing is approximate on purpose: '2 months ago' is easier to read than '59 days ago'. For an exact years/months/days answer use the Duration Calculator.
