Evernote – How to Add Link or Anchor Within the Same Note

There's no way to link to notes that will consistently work on all the clients. It's one of the most requested features, and it is "definitely planned" by the developers. ^[source]

There's a hack to doing it on the Mac by using the exploit of spotlight, however this will only work on the same Mac. As well as linking to notes using the web client, however this will force the notes to be opened up in a browser.

It happens every month on the same day at 12 AM. That means it won't be exactly every 30 days, since some months have 31 days, for example.

Each client's "days left in cycle" behaves differently. The Mac and iPhone clients will display the amount of days inclusively, while the PC and web clients display the amount of whole days left. For example, let's say that the time is 11 PM, on the last day (i.e. in 1 hour, the usage meter will reset), the Mac client will say "1 day left in cycle", while the PC client will say "0 days left in cycle". Similarly, on a month with 31 days, immediately after the meter is reset, the Mac client will say "31 days left in cycle", while the PC client will say "30 days left in cycle".
