Spreadsheet in, calendar out.
Koyomi turns the schedule someone handed you as a spreadsheet into a real calendar file. Drop in a CSV or Excel sheet, map the columns to title, start, end, location and notes, pick the time zone the sheet was written in, and download an RFC 5545 .ics that imports cleanly into Google Calendar, Outlook or Apple Calendar. Date parsing is deliberately forgiving — day-first and month-first formats, times with or without seconds, all-day rows — and the core is covered by unit tests so a wrong mapping fails loudly instead of silently shifting events.

Forgiving date parsing across regional formats, with explicit time-zone handling
Runs entirely in the browser; the conversion core ships with its own unit tests
The studio agent helped architect this system — ask it anything.
