About Ruwya Planner

Who writes Ruwya Planner, and why it is independent.

Ruwya Planner is an independent guide to calendars, reminders and planning: time zones, recurring payments, bank transfer cut-off times, maintenance windows and holidays across different calendars.

Who writes it

The guide is written by Hana Selwyn, a pen name for a planner who coordinates work and family across several time zones and two calendars. No financial or technical qualification is claimed.

About this address

This domain was previously used for a holiday-reminder app. This site is independent and is not connected to, endorsed by or speaking for that app or its developers. There is no app to download here.

How pages are written

General definitions link to Wikipedia. Banks, payment schemes and online services each set their own times and rules, so this guide describes how things generally work and asks you to check the details with your own provider.
