Goodness, there are several options to choose!
Let's examine a few on an event that has yet to occur and see what happens.
I've chosen a popular event- April the giraffe, who should give birth, well, someTIME.
She's on Live stream Here
She's definitely pregnant, although time frame of conception is unclear.
The world has been on standby since Feb 23. It's April 12 as of this post.
Let's ask the cards and see what system comes closest.
This Barbara Moore post covers several techniques:

Not leaving out the popular Biddy Tarot:

These are the most common (note there is even some overlap within these four) although part of really learning Tarot is finding what works for YOU.
I, for instance, do not equivocate Swords as Spring. That is Wands as far as I am concerned. My personal system is as follows.
For this exercise, I will follow these very popular links as written and see which one predicts this blessed event correctly. I've pulled one card, with the question,
"When Will April the Giraffe Give Birth?"
Answer: 4 of Wands (RWS tarot)
We could be looking at:
4 weeks, by Barbara Moore's Golden Dawn Inspired Timing post (Or as the general term, Summer- hope not, for poor April)
Between April 11-20 (3rd decan Aries) by Lisa Eddy's post
4 Days (it's 10:30 am Wed, Apr 12 EST) Or in Aries or fire sign dates as of this writing by Biddy's post
All very good (and close!) answers in this race - Stay Taroted in for who gets the closest!
-Barbara's post did offer other methods- such as
Narrative, (4w= during a celebration?)
Minor Arcana weeks = 4th week of Summer
Suit, Court, and Major Timing= 4 weeks
Golden Dawn= (alternate- if I read the post correctly) Full moon during Noon to Twilight? New twist, it is the Full Moon, after all
-I followed Lisa Eddy's very easy to use cheat sheet for her answer.
-Biddy's post offers some Astrology tips = Wands can mean Aries, which we are in until April 19
-Lisa Allen's method also concurs with a four day timing period, and her more traditional method is open to change out season and suit, allowing me to have my Wands= Spring. ** spoiler, it means by April 20 there will be a new giraffe foal! :-)
UPDATE- APRIL 15, 2017 BABY BORN! CARD TIMING WAS CORRECT FOR FOUR DAYS OR BY APRIL 19!!!! CONGRATS TO APRIL THE GIRAFFE!!
+ Barbara's timing post of when, if for the 4w is also correct "after a holiday"-
We just had Passover. Neat!
