[Bug] Unable to log historical cycle dates

[sreeramachandramurthy]

HealthLog version

v1.38.24

Deployment type

Self-hosted (Docker)

What happened?

I am manually trying to add historical cycle (January 26th, 2026 which is before current day)

1. healthlog incorrectly assumes I am logging Day 2

2. I proceed and click on Save and healthlog discards the action

Expected behavior

healthlog should save the Cycle as a historical date or show an error message "Cannot log historical dates"

Steps to reproduce

1. Login into healthlog (as a Female user)
2. Navigate to Cycles
3. In the Calendar tab, navigate and click on an previous date (January 26th in this screenshot)
4. Popup incorrectly suggests Day 2. Ignore the message.
5. Click on Save. Popup closes but date is not saved.

Relevant logs / screenshots

No error logs. Below log is captured after reopening the date and clicking on the save button again.

Another observation, after adding January, February, March cycle start dates, the popup started displaying My period ended this day button for month of May. This button was not available / visible before.

Thanks, and the log you attached is worth a lot here, because it rules out the obvious explanation.

That request succeeded: POST /api/cycle/day-logs came back 201, the server wrote a row, and "existed": false says it was a fresh one rather than an update. So at least on that attempt the entry was stored. Whatever went wrong is either on the first attempt, which produced no request at all, or in what the calendar shows you afterwards, and those are two very different bugs.

Two things would separate them, and both are quick:

1. After saving that January date, reload the page and open the same date again. Does the sheet come up with your entry in it, or empty?
2. Same question for the history list rather than the calendar grid, if that view shows January for you.

If the entry is there on reopen but the calendar stays blank, the row is stored and the calendar is not showing it. That is my main suspicion, because a date that sits before your first recorded cycle belongs to no cycle, and the calendar is drawn from cycles.

The "Day 2" label is a separate bug and you are right about it: that number is counted from your current cycle, which says nothing about a date in January. It should either show the day within the cycle that date actually belongs to, or no number at all.

One more thing that would help: on the very first attempt, had you selected anything in the sheet, a flow or a symptom, before pressing Save? The missing request on that attempt is the part I cannot explain yet.
