Entries before September 7, 2026 were reconstructed from Git history. Dates are change dates in Japan and may differ from actual release dates.
Security and usability improvements
The site moved to nitei.pages.dev. Links to the old address open the same page at the new one.
Pages open faster: the site is now served as ready-made files.
Web addresses in the description now open as links.
The settings of "Import .ics / zip" are now remembered on this device for each event.
After a calendar is loaded, changing the settings fills the answers again right away, without choosing the file again.
Changed settings are shown below the buttons even when the settings are closed.
Loaded calendars can now be removed, so a wrong file can be undone. Loading a file with the same name again replaces the earlier one.
The event edit page can no longer be typed into until it has loaded. Text typed while loading used to disappear.
Small buttons and links are easier to tap on phones.
Other sites can no longer embed Nitteigumi pages in their own. This blocks tricks that hide a page under another so you click it without knowing.
Easier filling by time
In the settings of "Import .ics / zip", "By a time for each symbol" can now check whether the time is free or busy.
The time tool in "Fill date range" now reads as one line, such as "dates overlapping 19:00-23:00 get ✕". It uses the dates' own times, not your calendar, and can pick the other dates too.
Applying in "Fill date range" now says how many dates were filled.
Choose symbols by the free time in your calendar
In the settings of "Import .ics / zip", each symbol can now have the time that must be free. Legends that give each symbol its own time, such as "◎ all day, ○ evenings only", are filled in just by loading your calendar, and a symbol can have two times. "Fill from free time in your calendar" has moved here from "Fill date range".
"Fill from your calendar" in "Fill date range" now reads as one line, such as "busy dates from 19:00 to 23:00 get ✕". It can pick free dates too.
Added a contact form
Inquiries can now be sent through a form (Google Forms), with no email app needed.
Added a second form for screenshots and other images, for people signed in to Google. Text-only messages still need no sign-in.
Calendar-based bulk answers and readability fixes
Added a way to fill answers from your calendar by giving each symbol a time window, under "Fill date range". For events that split time by symbol, such as "◎ all day, ○ 20:00-24:00, △ 23:00-26:00", each date gets the first symbol, from the top, whose time has no overlapping event.
You can now change every date where a calendar event overlaps a chosen time to the symbol you pick.
Fixed the selected ✕ being hard to see in dark mode, and made weekend dates on the calendar easier to read.
Opening a link to an event that no longer exists now shows an explanation and a link to create a new one.
Added an icon for the iPhone home screen.
Dates with only a start time now count as three hours in the time-range bulk answer too, matching the calendar import.
Improved English labels and behavior after updates
Shortened the English response-list controls so they fit one row on phones.
If a page opened before a site update stops working, it now reloads automatically and keeps what you were typing.
Pages open faster on return visits by reusing files that have not changed.
Easier-to-read response list
Removed extra column width around wrapped respondent names.
Response-list controls no longer run off the screen on tablets or phones held sideways.
Moved "↑ Respond" next to the heading and sized the display controls to fit one row on phones.
Compact header and general note position
Made the create and edit header a compact bold monochrome title, freeing space at the top.
In the response list, you can now show general notes under each name or below the table.
Clearer event titles and date options
Event titles now use bold black or white text in a compact bordered heading.
Results now highlight the dates with the highest combined total of ◎ and ○ answers, including ties. No dates are highlighted when all totals are zero.
Calendar drag selection fix
Dragging back can now leave just one date selected. Moving past the starting point restores the selection from before the drag.
Sharing and early update history
Added a small link to open a post introducing Nitteigumi.
Expanded the update history back to the initial implementation in April 2026.
The results section now also shows the event name and description.
Moved updates and sharing links to the bottom of the page and shortened the suggested post text.
Reduced vertical spacing across creation, responses, history and other pages, including tighter mobile toolbars.
Release history
Added a release history page in Japanese and English.
Calendar imports and drafts
Improved overlap detection for overnight date options, all-day events, and recurring calendar events.
Drafts and undo/redo history now survive switching between Japanese and English.
Retrying a new response after a connection error no longer creates duplicates, provided the page has not been reloaded.
Added size limits when importing calendar files.
Consistent time controls
Desktop time inputs, apply actions, and undo/redo now follow the same layout as on phones.
Restored descriptive Japanese answer-option labels that fit on one line on phones.

Date labels and other headers can stay visible during horizontal scrolling.

Moved the theme switch to the top left without making it follow page scrolling.
Dedicated search icon
