2 weeks events are those that are listed under the C.S. Events button in-game. Other than the very first week these events are cross-server events (except for ingot rush). Eventually, you will get the hang of everything that goes into each event.
I have listed all events that are current with where I am in my gameplay, it is possible that your server has not had some of these events yet or has events that I do not have listed here.
I've tried to list items/ actions for each event below but I am sure I have forgotten something!
Earnings + Guild Exp+ Infirmary/ Estate
Earnings: This will calculate your growth in earnings, I suggest not trying to fool the system they use your highest ever earnings, not your earnings when the event starts.
EVERYTHING affects earnings
Upgrade your infirmary symptoms now as that will give you a market boost
Upgrade your retainer deployment (abacuses) SSR max level=200
Upgrade your estate courtyard market scroll items
Upgrade your estate soil/heredity levels (spend the market design scrolls)(or do this when the estate is also running the events are always timed together)
Guild Exp: This is based on the experience gained by your guild during this time:
Do all constructions (even the ones that cost gold and hammers)
If 15 guild members can spend $1 at the top up you can grab the "free" hammers from the guild rewards.
Send all trades AND max them out
You can gather gold bars to send for trades from doing constructions or doing escort/plunder.
You can get trade flags from the Voyage event.
Infirmary: Based on your "hearts" increase
Saving up Patient manuals for several event turns can get you a win here.
Patient manuals are available in the conquest shop as well as several other exchange shops.
Estate: This event is based on your increase in estate prosperity
Upgrade your crop/Animal levels
Use any special buildings you received from events
All upgrades to the estate will give you some boost though not a huge one for most things!
Retainer + Aptitude/Grandchild
Retainer: calculated based on your retainers growth in all-time high earnings (no removing your beast and re-adding it will not boost your earnings)
Increasing aptitude
leveling up
attire
Increasing star level
Cooking skills (individual AND at the Inn)
Upgrading auras
Beauty Mien skills
Aptitude
Saving Aptitude pills
Fishing
Upgrading beasts
Attire
Beauty Mien skills
Intimacy+Heir
Intimacy
Beauty attire
Use combs/Hair sticks and earnings
Use those saved-up travel "stamina pills"
This has the added side effect of getting you the twins + select beauty perk, so clear your heirs before doing this then go make some babies.
Heir
Use bath bottles or travel blessings
Use the buddy system, work together with a guildmate who has similar intimacy to you and marry each other's kids.
Feast+Restaurant+Ingot
Feast
Hold fests
Attend feasts
Upgrade your beauty banners to increase points.
Restaurant
Based on the number of silver ingots gained during the event. No, you cannot get more points by only collecting ingots during the event.
Using "nice wine", only use a few at a time and then spend the ingots.
Ingot
Buy things!
Looms are quite expensive and a great way to win the ingot rush. You can have 35 looms at 5k a pop.
Charm + Guild trade war/Escort (most likely to be a 2-day event)
Charm
Donate
Rouge/ Sachet
Beauty attire
Guild Trade War
Time to use those challenge tokens. You can use them in the trade war section as well as on the event page.
Escort
You get points for escort as well as plundering.
