Profile

I built a small, MIT-licensed app to end ad‑hoc "when are you free?" timezone discussions for cross-TZ teams. Heavy scheduling tools already exist, but for quick overlap checks they’re overkill.This app shows a 7×48 weekly grid (30‑minute slots). You click to select availability, then share a single URL. The viewer sees your ranges in their own timezone, and the app keeps a "sender timezone" badge for context.Highlights: - Ad‑hoc, zero‑signup flow (state in URL) - Timezone‑aware display (detected vs. sender) - Half‑hour slots, overlap checks, range preview + delete - DST‑safe (Intl‑based) without external date libs - MIT licensedRepo: https://github.com/synweap15/calendar-convert Live: https

Ad‑hoc availability app – timezone‑aware weekly overlap (no login) is positioned in show hn launch, a segment that rewards a clear, focused offering.
