The @sunofseldo account on Twitter Mastodon BlueSky tweets posts encouraging things every day during the darkest days of winter, usually about how much daylight there is left. This tool helps @seldo compose the posts , and may help you if you want to do something similar! and is hard-coded to send from one account until BlueSky makes OAuth less painful.
(Please read all of these before starting!)
1. Log in with BlueSky using a BlueSky account you intend to send the posts from.
Do not use your primary BlueSky account, this app is a side project and has not been security audited and I do not want responsibility for access keys to your personal BlueSky account.
2. Click "change location" and drag the map until you're exactly where you want it to be. Latitude (north-south) is what affects the length of the day, but longitude (east-west) will automatically select the right time zone for you.
3. Enter posts! You can click on any date to change it. Hitting Enter will save a post and move to the next one. Hitting Shift+Enter will save the post and go to the previous one if you find it easier to work backwards.
The app will give you suggestions about important events and milestones each day, and you can check @sunofseldo's posts from previous years for examples of posts people found particularly cheerful.
