One Calendar problem and three suggestions...
Love your calendar!! I've been using it for about 16 years as as a firefighter with an 8 day shift rotation, yours was (is?) the only calendar that allows me to select my customized "Repeat every 8 days" so as to populate my recurring shifts (and therefore the rest of my other life's regular events) for my whole career easily. Thank you!!
First suggestion, add Calendar to the "product list" on your feedback list at https://yahoo.uservoice.com/ so I and others can provide specific feedback on Calendar issues and make sure it will go to the right people to have it dealt with!! Meanwhile, I'll hope and appreciate it if you will pass on the following items to the right go to guys!
Second, on your Search Calendar page, there is a Refine by Date option, with date selection provided by a monthly drop down calendar...but if I want to search back for a list of things that has occurred over the past 10 years (eg specific medical appointment) I have to click back 120 months to regress the months back to that search beginning date. My suggestion...include the ability to select/scroll back with an earlier years back arrow too and/or allow typing in the earlier date parameter in the box.
Third suggestion....I'd love to have Yahoo Calendar as an app for my phone! I've tried to sync your calendar with other phone calendars but it never seems to work right.
Finally, there has been an issue with "Editing Recurring Events" for many months now. Even though I select "This Event Only", it applies the changes to "This and Future Events".
Thank you for your time and assistance!
