How it works

Each sign counts calendar days since the last time something happened: yesterday is 1 day ago, whatever the hour, the same way timeanddate.com and calculator.net count. If you gave a time and it's been less than a day, the sign shows hours, then minutes. Clock changes can't make a count jump, because days come from dates, not hours.

"It happened again" resets a sign. You can set an earlier date and time and add a note; if the time is before the last one, it goes into the history without changing the count. Every reset stays in the history, with the gap before it. "Longest" is the longest gap so far, and "Usually" is the median gap, which one odd gap can't skew. Neither is a score: a long gap since watering the plant is not a win.

Questions people ask

How are the days counted?
By calendar date: something that happened yesterday was 1 day ago, whatever the time. Under a day, a sign with a time shows hours, then minutes. That's the same rule as timeanddate.com's and calculator.net's day counters, which leave the end date out by default.
What does usually every 6 days mean?
It's the median of the gaps between the times you've logged, so one unusually long or short gap doesn't pull it off. It appears once there are two complete gaps.
Can I log something that happened earlier?
Yes. Choose the date and time in It happened again. If it's earlier than the last time, it goes into the history and the count stays as it is.
