Here is an example of a Holiday archetype in D&D, for several more examples check out the link.
Charity
Celebrants are expected to either spend time helping the needy or to make large donations to worthy causes. One or both may be available, at the DM’s preference. If volunteer work is the preferred method of charity, they must spend 8 hours a day doing so for the duration of the festivities, but pay no additional lifestyle expenses. If donations are preferred, the character must spend 50% more than their usual lifestyle expenses (or more, if the character is known to be particularly wealthy; characters who are stingy do not gain any benefit) per day of the festivities, with the donations going to the poor or to charitable organizations.
Benefit: After the festivities have ended, the character’s generosity gives them a general sense of satisfaction and an appreciation of what they have. After the holiday is over, the character gains a number of d6’s equal to the days spent on charity. The character can roll a die and add the result to a Wisdom or Charisma ability check or saving throw, then the die is expended.
