  description

  Here's how Sundial works:
  
  After installing and signing up, Sundial appears in the left column of Google Calendar.
  
  1️⃣ Add Multiple Timezones to Google Calendar
  Search for a place or timezone and Sundial adds that timezone to Google Calendar. Add as many as you need. Rename them as you'd like. Reorder them whenever.
  
  2️⃣ Share Times From Time Blocks
  Turn "Share times" on in the sidebar. Then drag time blocks on your calendar. Sundial turns them into copyable text, and can adjust it to any timezone. No more timezone mistakes. Here's an example of the text:
  
  Mon: Jan 2: 9-11am EST
  Tue, Jan 3: 8-9am EST
  
  Need to adjust to another timezone? Search for a place or timezone in the Sundial, and your copyable text updates instantly. Here’s how it looks:
  
  Mon, Jan 2: 3-5pm CET / 9-11am EST
  Tue, Jan 3: 2-3pm CET / 8-9am EST
  
  3️⃣ Bulk Create Calendar Holds
  Turn "Share times" on in the sidebar. Then drag the time blocks on your calendar where you want the holds to be placed and click "Create holds". Add your event details as normal and once ready, click "Save holds". Sundial will save the calendar holds for each selected time all at once.
  
  4️⃣ Bulk Delete Calendar Holds
  Click on any existing event with the word "Hold" in the title. Then click "Select holds to delete." Sundial displays all holds with the matching title, allowing you to quickly select and delete the ones you want.
  
  5️⃣ Reusable Workspaces
  Save your commonly used calendar setups (calendars, timezones, and layout) as reusable workspaces. Open them with one click. Name them to stay organized.
  
  6️⃣ Highlight Events with Issues
  Instantly highlight calendar events for missing video links, rooms, guests not attending, etc. 
  
  7️⃣ Export Events to Google Sheet (Calendar Audit)
  Export events to a Google Sheet in a single click – formatted for a calendar audit and instantly ready for your customization and review.
  
  8️⃣ See Proposed Times Overlaid on Your Calendar
  Give Sundial dates and times mentioned in text and it visually displays them on your calendar. No more remembering proposed times or timezone conversions.
  
  ➡️ Sundial Pricing
  - Free Plan: 75 credits per month. That's about 10 meetings. Most actions use 1 credit.
