)

cstime provides date time functions for public health purposes.

The core functionality is consistent time conversion between :

• Date.
• Isoyear, isoweek, isoyearweek.
• Season week.

It also provides functions to generate rolling dates for computing the weekly, bi-weekly, 4 week averages.

cstime is part of the csverse package suite.

library(cstime)

To convert a date to isoyear:

To convert a isoyearweek string to isoyear/isoweek:

isoyearweek_to_isoyear_c("2021-02")
isoyearweek_to_isoweek_c("2021-02")

To convert a season week to isoweek (and reverse):
