What Research Says About Distance and Friendship
Roberts and Dunbar (2015), Managing Relationship Decay, followed 25 young adults and 1,291 network members over 18 months during the transition from school to university or work. Leaving the hometown did not itself explain declining friendship closeness. Contact and shared activities showed context-dependent associations. This small observational cohort supplies neither a universal predictor ranking nor contact-frequency minima.
A Draft Rhythm You Both Choose
This tool is an editorial, unvalidated scheduling aid. It helps turn an agreed intention into draft dates. A calendar entry cannot guarantee a conversation, an answer, or lasting closeness. Ask what contact your friend wants and choose a rhythm that works for both of you.
The tool compares your selection with weekly contact for its 5 group, biweekly for its 15 group, and monthly for its 50 group. Those are product examples, not research-derived minimum requirements. Monthly contact is not presented as sufficient for most friendships, and weekly contact is not reserved as a scientific rule for an inner circle.
A slower selection remains available and still generates a plan. Its comparison flag means only that it is less frequent than the editorial example. It does not predict friendship failure. This page also makes no universal claim that frequent short contact works better than a longer, less frequent conversation.
Candidate Call Windows
The algorithm looks for times between 08:00 and 22:00 in both local time zones and prefers evenings and weekends. This is a planning rule, not evidence of your waking hours or availability. Review each candidate against work, sleep, caring responsibilities, and time-zone changes before agreeing a call.
If no window fits the tool’s rule, the plan substitutes asynchronous contacts for live calls. You can use the output as a draft and arrange a different time outside the tool.
Channels According to Your Preferences
The plan rotates among the channels you select. Calls require a shared time; voice notes and texts can be answered later; postal messages need delivery time. These are practical differences, not a ranking of emotional quality. Agree formats that both people welcome, including accessibility needs and a preference for less contact.
Review the Calendar Export
The .ics file is generated locally from your draft events. Downloading it sends no message to your friend, books no visit, and creates no live calendar subscription. Check the dates, time zones, event counts, and alert settings in your calendar after import. When importing a revised file, manage previously imported events to avoid duplicates.
Calendar apps differ in their import and alert behavior. The generated file and a successful download do not by themselves establish Google, Apple, or Outlook client acceptance.
Calculation, Browser Saving, and Shared Links
Ordinary input and .ics generation happen locally. The optional save toggle stores settings in this browser’s localStorage. Turning it off stops future writes but leaves the saved copy. Use “Clear saved settings” to remove that copy and turn saving off; your current draft stays in this tab. Avoid saving personal details on a shared device.
Copying a shared link encodes the plan input, including your friend’s name, as a URL parameter. Base64 is not encryption. Recipients can read the data, and opening the link sends that URL to the website; URLs can also appear in browser history and logs. Use an alias and leave out information that should remain confidential.
