Add To Calendar

About

Add To Calendar

Instantly add events or appointments to your Google Calendar or other calendar (iCal, .ics) with the click of a button without retyping the title, date, time or location of an event.

Click on the "Add To Calendar" button 📅⁺ in the Chrome Toolbar on a website. It will scan the website using Intelligent Technology to find event information such as title, date, time and address.

NOTE: If you do not see the extension icon on the Chrome toolbar then click on the "Extensions" icon that looks like a jigsaw puzzle piece 🧩 on the Chrome toolbar. Look for "Add To Calendar" and then click on the pin icon 📌 next to it.

9/8/2021 - Version 0.9.8 
+Fixed some license issues.

Version 0.9.7 - 4/7/2021 - Added identity.email permission because Google is deprecating Chrome Web Store payments. So setup for new payments processor. Also the Add To Calendar extension can now find event data in "application/ld+json" if available on the website. Also the extension can now read event data in iframes if they are from the same domain. Also the extension no longer adds H2 elements to the document for IMG tags with title or alt attributes. Also added matching for a new thin dash – that is used on Google's events page for the time (ex: 7:30 – 11:59 PM) when selecting event text on the right side. Also added Dark Mode support.

Version 0.9.6 - 12/5/2019 - Links on popup were going to the wrong page to purchase "Add To Calendar" extension. Also one link was not opening because it did not have target="_blank". Fixed.

Version 0.9.5 - 1/19/2019 - Now finds event information in IMG ALT tags if there. Also improved finding of event information in highlighted text by removing   from elements. Also improved matching of start time and end time located in same element.

Version 0.9.4 - 1/15/2019 - Fixed so that "1-3 p.m." would not match a date by looking for it not to match "p.m." instead of just "pm". Also fixed so that "Jan 10-12" does not match a time of "10-12".

Version 0.9.3 - 1/10/2019 - Fixed where Europe style dates of "23-25 February" were being skipped because were being matched with "23-25-" style matching. Also fixed where the extension would detect "01/25/2019" as a Europe style date of dd/mm/yyyy because of the leading 0. Now calculates that the 25 is too large to be a month.

Version 0.9.2 - 12/21/2018 - Fixed some bugs where times like 5-7:00 were sometimes matching a date of 5-7. Also fixed a few other bugs where dates like 12/25-12/29 were sometimes matching 12/25/12.
