Since When?!

About

Since When?! adds a small panel to every Google Calendar event popup showing the information Google hides by default.

WHAT YOU GET
  • Creator — who made the event and their email address
  • Created date — when the event was first added to the calendar
  • Last modified — if the event was edited after creation, you'll see when (useful for spotting if you were added to a meeting after it was scheduled)
  • Find invite — a one-click link to search your Gmail for the original invitation email

MULTIPLE ACCOUNTS
Sign in with more than one Google account. Since When?! will check all of them when looking up an event, so it works whether you're viewing a personal or work calendar.

PRIVACY
No data is stored or transmitted beyond your own Google account. Your calendar data never leaves your browser.

LANGUAGES
Available in English, Spanish, French, German, Portuguese, Italian, Japanese, Korean, Chinese, Dutch, Polish, Russian, Swedish, and Turkish.

FREE FOR GMAIL ACCOUNTS
Free forever for @gmail.com accounts. A 30-day free trial is available for Google Workspace accounts, after which a one-time payment unlocks the extension permanently
