Habit Tracker Streak Calculator

Why a single last-done date already shows a broken streak here

With a last-done date of September 2, 2026 and a target of 5 days per week, this streak shows status 'Broken' -- 14 days have passed since the habit was last logged, which is far beyond what a 5-day-per-week target allows before the streak lapses.

At a target of 5 days per week, the maximum reasonable gap between two logged days (accounting for weekend rest days in a typical 5-of-7 pattern) is roughly 2-3 days before the streak should be considered broken -- 14 days since the last log is nearly five times that gap, which is why the status shows Broken rather than 'At risk' or 'On track.'

The note 'Log today to start a new streak' reflects this tool's actual function: it's not trying to reconstruct or salvage a lapsed streak, it's telling you the current streak has ended and a new one begins whenever you next log the habit.

Why one date can't fully capture streak history

One last-done date cannot reconstruct a multi-week history. Planning only. This tool only knows the single most recent date the habit was completed -- it has no record of every day across past weeks, so it can't tell you your actual completion rate, your longest streak ever, or exactly which specific days you've been consistent versus not. It answers one narrow question: is the streak still alive as of today, based on the last logged date alone.

A more complete habit-tracking system would need to log every single completion date (or non-completion) to calculate real historical statistics -- this calculator is a lightweight planning check, not a substitute for that kind of full tracking history.

The specific gap-tolerance threshold implied by 'Broken' status scales with your target-days-per-week setting -- a 7-day-per-week target (aiming for every single day) would flag a broken streak much sooner than a 3-day-per-week target would, since the expected gap between logged days is inherently smaller for a more frequent target.

Using this alongside a fuller tracking system

This quick check is most useful as a simple nudge -- a fast way to confirm 'am I still on track' without needing to open a full tracking app or spreadsheet, especially right before the gap becomes large enough to matter.

For planning actual focused work sessions that could be part of building the habit itself, the Pomodoro Interval Planner is a related tool for the follow-through side.
