I'm not sure if I'm overcomplicating this. I'm talking about events in the past, and I want to use relative time markers within that time frame. For example, "the day after that", or "the day before that", or "a year later". I'm not sure if I can use 明日【あした】, 昨日【きのう】 and 来年【らいねん】, because as I see it, I would be referring to the present timeline, the next day/previous day/next year for me. Is this so, or am I overcomplicating it?
Is there a separate set of words for talking about relative time in the past, or is this something that is simply understood from context?
