Clockwise alternative
Clockwise is gone. Cross-timezone meetings aren't.
Clockwise shut down on March 31, 2026. The part of it that mattered for distributed teams — finding a time that works across multiple zones — still does. intltime keeps that core, drops the calendar OAuth and per-seat pricing, and adds DST-stable share links and holiday awareness for religious calendars Clockwise never covered.
Free · No login · No calendar OAuth
What carries over · what doesn't
Feature-by-feature.
The honest version — including the things Clockwise did that we don't, and where to go for those instead.
Free, no login required
Clockwise: required Google/Microsoft OAuth.
DST-stable share links
Clockwise stored wall-clock; the same link could shift after a DST change.
Cross-timezone working hours math
AI-aware natural language scheduling
Public-holiday awareness
Both surfaced national holidays per participant.
Religious-holiday awareness (Diwali, Eid, Lunar NY)
intltime ships a curated affinity map per country.
5,000-city dataset with sunrise/sunset
Embeddable widgets (clocks, countdowns, world strips)
Calendar OAuth + internal busy-time detection
For this, use the AI built into Google Calendar or Microsoft 365.

FAQ
Common questions.
Why did Clockwise shut down?
Clockwise announced on January 14, 2026 that it would shut down on March 31, 2026. The team cited the difficulty of competing with calendar AI now built directly into Google Calendar and Microsoft 365.
Is intltime a direct Clockwise replacement?
No — and on purpose. Clockwise was a calendar-resident scheduling agent with OAuth into your Google/Microsoft work calendar. intltime is a no-login cross-timezone planner. We solve the meeting-window problem (find a time that works across N zones) without the calendar access. For internal team scheduling inside one timezone you'll want one of the integrated AI assistants in Google or Microsoft.
What does intltime do that Clockwise didn't?
DST-stable shareable links (same URL means the same UTC moment, even after a DST shift), per-participant trust badges for public + religious holidays (Diwali, Eid, Lunar NY, Passover, Rosh Hashanah, Yom Kippur, Ramadan), 5,000-city dataset with sunrise/sunset and moon-phase data, a 24-hour /converter for any pair of zones, and embeddable widgets you can drop into Notion or a wiki.
Do I need to sign up?
No. There's no account, no email, no calendar OAuth. The link is the artifact — paste it in Slack, send it in an email, drop it in a calendar invite. Whoever opens it sees the same plan.
What's the catch on pricing?
There isn't one yet. The site is free to use indefinitely. We may eventually offer paid features for team workflows (shared team libraries, custom domains for embeds), but the core planner stays free.
Can I import my Clockwise data?
Clockwise's calendar overlay didn't store much that's portable — it was mostly an in-calendar layer. If you want to recreate a recurring cross-zone sync you set up there, just paste the participant cities into intltime's planner and use the AI prompt or drag the grid.
