Longer guide I found that goes into more detail (more noob friendly):

  1. THIS WORKS ON ALL GAME REGIONS.

  2. Update Animal Crossing to the latest version available. This will work on patch 1.1.1 and up. This will not work on 1.1.0 and below.

  3. Download JKSV.nro and put it in the folder named "switch" that is already on the root of your SD card. https://github.com/J-D-K/JKSV/releases

  4. Optional But Recommended: Backup your animal crossing save just in case you mess anything up. To Backup your Animal Crossing Save Open JKSV from the homebrew menu Enter the "Device" folder and then select animal crossing. Go to "New" and then press A to backup. Then name your backup. If for any reason you need to restore this save backup Enter the "Device" folder and then select animal crossing. Select the name of the file you made when you backed it up and then press Y to Restore. Some people have reported you may have to hold L & R when trying to create or restore backups. This was not the case for me but some people may need to do it, no idea why.

  5. Open JKSV again and make a backup of your BCAT file for animal crossing, To backup your "BCAT" Enter the "BCAT" folder (NOT the "Device" folder!!!) and then select animal crossing. Go to "New" and then press A to backup. Then name your backup. Some people have reported you may have to hold L & R when trying to create or restore backups. This was not the case for me but some people may need to do it, no idea why.

  6. Go to your computer and insert your SD card, Open the JKSV folder on the root of your SD card, then open the Animal Crossing New Horizons folder and then open the folder you named when you backed up your BCAT. You should see a file called passphrase.bin

  7. Download the needed BCAT files (I don't think I can link those, so google)

  8. Take the "directories" folder from the file you downloaded above and drop that in your BCAT backup folder. Your BCAT backup should now have only the files called "directories" and "passphrase.bin" in it. Delete any other other files in there except those 2.

  9. Go back to your switch and restore your BCAT with JKSV. To restore your "BCAT" enter the "BCAT" folder (NOT the "Device" folder!!!) and then select animal crossing. Select the name of the file you made when you backed it up and then press Y to Restore. DO NOT RESTORE YOUR BCAT IN "DEVICE" THIS WILL ERASE YOUR SAVE DATA. MAKE SURE YOUR IN "BCAT" WHEN YOU RESTORE IT.

  10. When you launch the game you should now have the Easter event. Have fun! You DO NOT need to follow any steps below if it is working. You're Done.

  11. FOR ANYONE WHOSE EASTER EVENT IS NOT WORKING: Simply set your clock back to March 31st, enter your game. Close out of the game. Set your clock back to the present date - your event should be working now OR just reboot your switch.
FIX FOR MAC USERS:

If anyone is on a Mac and the event is still not working after fixing the switch clock then you should try either using Windows or doing the following if Windows is not an option.

Once you have moved the files you downloaded into the BCAT folder on your SD card open up terminal on your mac and run this command:

sudo chflags -R arch /Volumes/SDCARD

The SDCARD part is the name of your card. So for example mine is called TXNAND so I would run:

sudo chflags -R arch /Volumes/TXNAND

It will then ask you to enter your computer password. Type it in and then press enter. It will look like its done nothing, there is no confirmation or anything. From there put the card back in your Switch and restore the BCAT. This is the same thing I have had to do when updating firmware while using a Mac. The Switch wont recognize the firmware files until I run this command. Thanks to liquid_kore for this Fix.

ANOTHER FIX FOR MAC USERS:

If the above steps did not work you can also try this fix provided by hater_of_icecream. For those who usually use macs with their microSD card, after placing the directories folder into your BCAT folder, go to a windows PC and do the steps here: "https://gbatemp.net/threads/how-to-fix-archive-bit-for-all-sd-files-and-folders.515258/" then put the micro sd card in your switch, go on jksv and restore the BCAT and there you go!

Nothing special to do for windows users, nothing "technical" in here, only for few user mac with the right flags on folders, but it's the same for all files of CFW
The most important it's to backup the save, and work on a copy, and place the folder directories in the good place :)

Is someone going to come up with an easier way to do this? I don't want to remove my SD card and fiddle with files for every event.

You can also ftp it if you don't want to remove your SD card. And yeah someone might make some homebrew out of it in the future. But that's not certain.

Also if you know what you are doing this whole process takes less than 5 minutes...

You simply can’t help everyone. People need to be able to help them self. So many times the guides been broken down even more yet people still don’t know what they doing or messing up their saves which has nothing to do with the event. Fml

That old post with the video should be put up in the OP to guide the others. Just a suggestion. It worked on mine by the way. Kosmos latest with the 1.1.1 update.

(Oui mais traduire une mauvaise doc c'est pas top :) )

Translate a bad guide is not good :)

De rien je suppose ? Comme je l'ai dis : "Pour les français : j'ai traduit et ajouter/clarifiés les étapes pour ceux qui sont sur XS os".
J'ai vu que beaucoup de monde galérait et, ayant réussit de mon côté après moult bidouillages... J'ai juste voulu aider avec le maximum d'infos et d'étapes qui m'ont permis de réussir. Je n'ai fait que traduire mes explications pour les anglophones.
