SYNCDATE is a web application for live two-way Google Calendar synchronization. Connect multiple Google accounts, select which calendars to sync, choose direction (one-way or two-way), and SYNCDATE keeps events aligned automatically in the background.
Built for professionals juggling multiple Google calendars across work, personal, and side-project accounts.

SYNCDATE CalensyncSYNCDATE's answer
SYNCDATE treats sync as silent infrastructure โ it shows proof instead of making promises. Every sync run is logged with stats, every error comes with a deterministic fix step, and every sync can be cleanly reversed with optional event cleanup. Most calendar sync tools are black boxes. SYNCDATE exposes sync health, freshness, and latency so you can verify it's working in seconds, not just hope it is.
Calensync's answer:
Open-source, infinite calendars, and cheaper pricing.
SYNCDATE's answer
A generous free-forever tier (2 accounts, 2 calendars) covers the most common use case at zero cost โ competitors start at $4โ12/mo. Privacy is the default: synced events show as "busy" unless you opt in to detailed copying. And if you ever want to stop, the Clean Exit flow removes all SYNCDATE-created events from your calendars โ no orphaned copies left behind.
Calensync's answer:
Pricing not based on number of accounts / calendars, as well as simply cheaper.
SYNCDATE's answer
Calensync's answer:
Freelancers, entrepreneurs that deal with multiple businesses and accounts, or anyone who has multiple google calendars.
SYNCDATE's answer
SYNCDATE was born from a real problem: juggling multiple Google accounts and constantly getting double-booked because calendars didn't talk to each other. Existing tools were either expensive for what they offered, opaque about what they were doing, or left orphaned events behind when you stopped using them. SYNCDATE was built to be the sync tool we wanted โ minimal, transparent, and safe to turn off.
Calensync's answer:
The story starts from frustration. I have multiple professional google calendars, as well as my personal one. On the professional ones, people can book events directly and, unfortunately, I had multiple conflicts. This lead me to first check for existing solutions and after being dissatisfied, deciding to create it myself.
No more conflicts between events since Calensync!
