ICS Calendar File Generator
Free tools for building calendar files and add-to-calendar links — nothing is uploaded, every file is built in your browser.
Single event → Add to Calendar
One event, one time — get a Google/Outlook/Yahoo add-to-calendar link plus a downloadable .ics file.
Recurring event .ics generator
Daily, weekly (pick the days), monthly, or yearly — build a repeating event as a downloadable .ics file.
Yearly birthday / anniversary reminder
A simple all-day event that repeats every year on the same date — no year-to-year drift.
