I use Evernote as my list manager and one of my electronic reference tools.

For ticklers, I use tags. I have a Tag called "Tickler" and then underneath that I have sub-tags "Days", "Months" and "Years". Under years I have 2013, 2014, 2014. Under Months I have 01-January, 02-February, etc. and then under Days I have 01, 02, 03, ...

I use a single note for each next action, and if it's a tickler, I add the relative day, month and year tags.

When it get to a particular day, or week, I can then select the relevant tags to see what's tickled for that day, or for the upcoming week.

I do also, add the date in between two hashtags (e.g. ##30 November 2012##) and I use TuskTools which automatically displays this tickler on my google calendar on that day. I can also put it at a particular time of day if that made sense.

Works perfectly for me.
