# Visibility/priority #
#######################
#
# This part describes when the news should be visible, and with what priority (how high in the list).
#

from 2021-06-28 for 1 month, priority= low
from 2021-06-28 for 2 weeks, priority= normal
from 2021-06-28 for 1 week, priority= high

before 2021-06-28, visible= false

#
# Other intervals of priority can/have to be specified.
#
# As a rule of thumb:
#  - priority high for up to 3 days, 10 days for very important events (FOCS) (appears top of the list)
#  - priority normal for up to 2 or 3 weeks (appears with high probability)
#  - priority low for as long as one wishes (probably invisible but sometimes can be if there is sufficient space)
#  - priority null makes the news invisible
#  - priorities may change several times (e.g. high for registration and for the event)
#  - this syntax can also be used for changing pictures, links, ...
#
# The syntax is the following
#   from DATE until DATE, priority= PRIORITY
#   from DATE for DURATION, priority= PRIORITY
#   for DURATION until DATE, priority= PRIORITY
#
# PRIORITY: high | normal | low | null
#
# DATE:
#   NUMBER MONTH NUMBER   (e.g. 22 June 2018)
#   ???-??-??             (e.g. 2018-06-22)
#
# DURATION:
#   NUMBER (day|days|week|weeks|month|months|year|years)
