If an event will occur in the future I might say:
There will be an event and it will have a number of features.
If it occurs in the past I might say:
There was an event and it had a number of features.
If it is occurring now I might say:
There is an event and it has a number of features.
What if I dont yet know the time of the event relative to "now"? Alternatively, what if I do not want to reveal if the event has occurred yet, but I do want want to describe it?
If I want to remain ambiguous about gender I can use the neuter form. Is there something equivilent in tense, or is there a selection of tense neutral words I can use instead?
