Age and Duration Labels in NOTAM Cards: Freshness at a Glance

2/12/2026

When you're triaging many NOTAMs, time context matters as much as content. We added Age and Duration attributes so you can quickly see how fresh a NOTAM is and how long it is expected to affect operations.

NOTAM cards with Fresh label

This improvement was built thanks to great feedback from our beta testers. Their day-to-day operational input helped us tune these labels for fast scanning in real-world workflows.

Where these labels appear

  • In list cards (in NOTAM airports pages), the Age label is shown as a compact badge for rapid scanning.
  • In detail view (in NOTAM details pages), Age and Duration are shown together with extra context.

New sorting rules

We also updated sorting labels and behavior to make ordering clearer.

NOTAM sorting options

"Most recent" is now "Latest Effective"

What used to be called Most recent is now labeled Latest Effective.
This reflects the real behavior: sorting by effective start time, newest first.

New "Latest Issued" option

We also added Latest Issued, which sorts by NOTAM issue time (issued_at), newest first.
Use this when you want to track newly published NOTAMs, regardless of when they become effective.

Sorting modes

Sort optionRule
Latest EffectiveSort by effective start timestamp (descending)
Latest IssuedSort by issue timestamp (issued_at, descending)
CategorySort by category hierarchy order, then subcategory order
ImportanceSort by affected-element impact priority (Pro) - read how it works

Important behavior

  • Before any selected sort is applied, list ordering first prioritizes NOTAMs active in your selected time range.
  • This means active NOTAMs surface first, then each group follows the selected sorting mode.

Age label rules

Age is calculated from issued_at to "now".

LabelRule
FRESH< 24 hours
RECENT>= 24 hours and < 14 days
AGING>= 14 days and < 90 days
OLD>= 90 days and <= 12 months
VERY OLD> 12 months

Duration label rules

Duration is calculated from startdate to enddate, unless a schedule exists (see cumulative duration below).

LabelRuleDetail text example
VERY SHORT< 24 hours6 hours
SHORT>= 1 day and < 7 days3 days
(no label)>= 7 days and < 90 days45 days / 2 months
LONG>= 90 days and <= 180 days4 months
VERY LONG> 180 days9 months
PERMANENTPERM NOTAMno duration detail

If the NOTAM end time is estimated, the badge appends EST to the duration detail.

Cumulative duration (aggregated)

Some NOTAMs are not continuously active. They may have active windows from schedule interpretation. In those cases, Notamify calculates cumulative active time. When this path is used, the duration badge adds the aggregated prefix (for example: Duration: SHORT aggregated 3 days).

This gives a more operationally accurate view for NOTAMs active in discrete windows.

Built with beta feedback

This feature started with a suggestion from one of our beta users, who asked for faster freshness and timing cues during high-volume NOTAM review. That single piece of practical feedback helped shape this release.
