US (FL): New app converts between dates and production week number
The production week number we use in horticulture is based on International Organization for Standardization (ISO) rules. Week 1 is the first calendar week of the year that includes a Thursday, the week runs seven days from Monday to Sunday, and there are 52 to 53 production weeks depending on the year.
Date Week is a new mobile app available at BackPocketGrower.org that does these date conversions for you. You can access the tool by clicking on the current production week icon on the home page of BackPocketGrower.org (Figure 1), or by clicking on Tools at the top right and then selecting “Date Week / Semana Fecha” from the list of calculator apps.
Figure 1. Click on the ISO number icon on the home page of BackPocketGrower.org to access the Date Week app.
Within the tool, you can convert from Date to Week or Vice Versa (Figure 2). The app is free and in both English and Spanish. Click on the En/Es button at top right to change language. Date Week was developed by the University of Florida IFAS Extension with web design by ThomasBaine Ltd. The tool was funded by industry partners in the Floriculture Research Alliance (FloricultureAlliance.org).

Try out Date Week on your mobile phone in the greenhouse or nursery. The University of Florida provides training on this and other apps in their online extension courses for growers (hort.ifas.ufl.edu/training). You will need internet access to run the tool.
