Here’s one thing, if you have a time frame you’re going to add a conditionality, so say the answer “June” is the result, June goes by and you become convinced it failed, and begin pouring in emotion, feeling miserable, angry, maybe even want to give up or con vince yourself it’s all futile, when in reality things may just have changed and shifted the time frame of the result, but it will still occur.
I tend to avoid putting anything in my own work that creates cut-outs. binary yes/no, pass/fail, on any element, because sometimes things are a bit more complex in delivery than expected, sometimes they can happen EARLIER but too much focus/intent is fixated on a date in time.
Calendar/clock time is also not always a strong area of spirits, cause-effect loops and astrological changes are easier for them to track.
This goes into why that may be, it’s an old post but so far I’ve not found anything that provides a better description of the reasons:
Note that none of what I’m saying here is about “let go, and let god” passivity, simply about not bringing a human concept of nailing down days and dates into a magickal working in a way that might be counter-productive.
