Thanks for confirming

Merkuro calender actually looks really good but yeah as of now it’s only on linux.

On a related note, is it possible to sync all my tasks on Simply (fossify) Calender with a Caldev server. Also does anyone know if there is a good client with Caldev sync on Windows ? I know thunderbird has that functionality, but I would prefer a standalone calender instead of an email client.

May I ask what is the spec of your VPS?
